This document discusses a system for classifying and compressing cardiac vascular diseases using soft computing techniques to enhance rural healthcare. ECG signals are collected from patients and features are extracted from the signals using discrete wavelet transform. The features are classified using an adaptive neuro-fuzzy inference system to identify normal signals or one of four abnormal conditions. Signals classified as critical are compressed using Huffman coding and sent to a hospital server for treatment, while mild cases are advised to see a cardiologist. The system aims to help identify heart conditions early to save lives in rural areas with limited access to healthcare.

PERFORMANCE EVALUATION OF ARTIFICIAL NEURAL NETWORKS FOR CARDIAC ARRHYTHMIA C...IAEME Publication
In this paper an effective and most reliable method for appropriate classification of cardiac arrhythmia using automatic Artificial Neural Network (ANN) has been proposed. The results are encouraging and are found to have produced a very confident and efficient arrhythmia classification, which is easily applicable in diagnostic decision support system. The authors have employed 3 neural network classifiers to classify three types of beats of ECG signal, namely Normal (N), and two abnormal beats Right Bundle Branch Block (RBBB) and Premature Ventricular Contraction (PVC). The classifiers used in this paper are K-Nearest Neighbor (KNN), Naive Bayes Classifier (NBC) and Multi-Class Support Vector Machine (MSVM). The performance of the classifiers is evaluated using 5 parametric measures namely Sensitivity (Se), Specificity (Sp), Precision (Pr), Bit Error Rate (BER) and Accuracy (A). Hence MSVM classifier using Crammers method is very effective for proper ECG beat classification.
AR-based Method for ECG Classification and Patient RecognitionCSCJournals
The electrocardiogram (ECG) is the recording of heart activity obtained by measuring the signals from electrical contacts placed on the skin of the patient. By analyzing ECG, it is possible to detect the rate and consistency of heartbeats and identify possible irregularities in heart operation. This paper describes a set of techniques employed to pre-process the ECG signals and extract a set of features – autoregressive (AR) signal parameters used to characterise ECG signal. Extracted parameters are in this work used to accomplish two tasks. Firstly, AR features belonging to each ECG signal are classified in groups corresponding to three different heart conditions – normal, arrhythmia and ventricular arrhythmia. Obtained classification results indicate accurate, zero-error classification of patients according to their heart condition using the proposed method. Sets of extracted AR coefficients are then extended by adding an additional parameter – power of AR modelling error and a suitability of developed technique for individual patient identification is investigated. Individual feature sets for each group of detected QRS sections are classified in p clusters where p represents the number of patients in each group. Developed system has been tested using ECG signals available in MIT/BIH and Politecnico of Milano VCG/ECG database. Achieved recognition rates indicate that patient identification using ECG signals could be considered as a possible approach in some applications using the system developed in this work. Pre-processing stages, applied parameter extraction techniques and some intermediate and final classification results are described and presented in this paper.

Training feedforward neural network using genetic algorithm to diagnose left ...TELKOMNIKA JOURNAL
In this research work, a new technique was proposed for the diagnosis of left ventricular hypertrophy (LVH) from the ECG signal. The advanced imaging techniques can be used to diagnose left ventricular hypertrophy, but it leads to time-consuming and more expensive. This proposed technique overcomes thesef issues and may serve as an efficient tool to diagnose the LVH disease. The LVH causes changes in the patterns of ECG signal which includes R wave, QRS and T wave. This proposed approach identifies the changes in the pattern and extracts the temporal, spatial and statistical features of the ECG signal using windowed filtering technique. These features were applied to the conventional classifier and also to the neural network classifier with the modified weights using a genetic algorithm. The weights were modified by combining the crossover operators such as crossover arithmetic and crossover two-point operator. The results were compared with the various classifiers and the performance of the neural network with the modified weights using a genetic algorithm is outperformed. The accuracy of the weights modified feedforward neural network is 97.5%.
Enhancement of ecg classification using ga and psoeSAT Journals
Abstract ECG signal classification utilizes for different predictions of heart diseases. These ECG signals have to be classified using different frequency bands according to different energy levels for better prediction of features. These signals have to be classified in different five bands P, Q, R, S and T. These sub-bands provide peak information available in different sub-bands. For the classification various approaches have to be implemented for filtration of signal. In the purposed work Adaptive filter has been implemented for the noise reduction from these signals. Classification of the ECG signal has been optimized using Genetic Algorithm and Particle Swarm Optimization approach. These approaches of classification provide better results i.e. 100 and 100 for 106o and 119o respectively for energy levels of ECG signal.

The electrocardiograph (ECG) contains cardiac features unique to each individual. By analyzing ECG, it should therefore be possible not only to detect the rate and consistency of heartbeats but to also extract other signal features in order to identify ECG records belonging to individual subjects. In this paper, a new approach for automatic analysis of single lead ECG for human recognition is proposed and evaluated. Eighteen temporal, amplitude, width and autoregressive (AR) model parameters are extracted from each ECG beat and classified in order to identify each individual. Proposed system uses pre-processing stage to decrease the effects of noise and other unwanted artifacts usually present in raw ECG data. Following pre-processing steps, ECG stream is partitioned into separate windows where each window includes single beat of ECG signal. Window estimation is based on the localization of the R peaks in the ECG stream that detected by Filter bank method for QRS complex detection. ECG features – temporal, amplitude and AR coefficients are then extracted and used as an input to K-nn and SVM classification algorithms in order to identify the individual subjects and beats. Signal pre-processing techniques, applied feature extraction methods and some intermediate and final classification results are presented in this paper.

In this project, we put forward a new automated quality aware ECG beat classification method for effectual diagnosis of ECG arrhythmias under unsubstantiated health concern environments. The suggested method contains three foremost junctures i ECG signal quality assessment ECG SQA based whether it is “acceptable†or “unacceptable†based on our preceding adapted complete ensemble empirical mode decomposition CEEMD and temporal features, ii reconstruction of ECG signal and R peak detection iii the ECG beat classification as well as the ECG beat extraction, beat alignment and Random forest RF based beat classification. The accuracy and robustness of the anticipated method is evaluated by means of different normal and abnormal ECG signals taken from the standard MIT BIH arrhythmia database. The suggested ECG beat extraction approach can recover the categorization accuracy by protecting the QRS complex portion and background noises is suppressed under an acceptable level of noise . The quality aware ECG beat classification techniques attains higher kappa values for the classification accuracies which can be reliable as evaluated to the heartbeat classification methods without the ECG quality assessment process.

This research task develops a mobile healthcare analysis system (PHAS) which combines both easy ECG signal measurement and reliable analysis of heart rate variability for home care purpose. The PHAS is composed by a health care platform (HCP) and a data system analysis (DSA) module. The HCP consists of a self-developed two pole electrocardiography (ECG) measuring device and the DSA a data processing unit for detection and analysis of heart rate variability. For the DSA module, the adaptive R Peak detection algorithm is proposed to reliably detect the R peak of ECG for HRV analysis. A number of features are extracted from ECG signals. A data mining method is employed for HRV analysis to exploit the correlation between HRV and these features. Experiments are conducted by establishing a database of ECG signals measured from 29 subjects under rest and exercise condition. The results show the PHAS’s significant potential in mobile applications of personal daily health care.

Classification of Cardiac Arrhythmia using WT, HRV, and Fuzzy C-Means ClusteringCSCJournals
The classification of the electrocardiogram registration into different pathologies disease devises is a complex pattern recognition task. In this paper, we propose a generic feature extraction for classification of ECG arrhythmias using a fuzzy c-means (FCM) clustering and Heart Rate variability (HRV). The traditional methods of diagnosis and classification present some inconveniences; seen that the precision of credit note one diagnosis exact depends on the cardiologist experience and the rate concentration. Due to the high mortality rate of heart diseases, early detection and precise discrimination of ECG arrhythmia is essential for the treatment of patients. During the recording of ECG signal, different forms of noise can be superimposed in the useful signal. The pre-treatment of ECG imposes the suppression of these perturbation signals. The row date is preprocessed, normalized and then data points are clustered using FCM technique. In this work, four different structures, FCM-HRV, PCM-HRV, FCMC-HRV and FPCM-HRV are formed by using heart rate variability technique and fuzzy c-means clustering. In addition, FCM-HRV is the new method proposed for classification of ECG. This paper presents a comparative study of the classification accuracy of ECG signals by using these four structures for computationally efficient diagnosis. The ECG signals taken from MIT-BIH ECG database are used in training to classify 4 different arrhythmias (Atrial Fibrillation Termination). All of the structures are tested by using the same ECG records. The test results suggest that FCMC-HRV structure can generalize better and is faster than the other structures.
Utilizing ECG Waveform Features as New Biometric Authentication Method IJECEIAES
In this study, we are proposing a practical way for human identification based on a new biometric method. The new method is built on the use of the electrocardiogram (ECG) signal waveform features, which are produced from the process of acquiring electrical activities of the heart by using electrodes placed on the body. This process is launched over a period of time by using a recording device to read and store the ECG signal. On the contrary of other biometrics method like voice, fingerprint and iris scan, ECG signal cannot be copied or manipulated. The first operation for our system is to record a portion of 30 seconds out of whole ECG signal of a certain user in order to register it as user template in the system. Then the system will take 7 to 9 seconds in authenticating the template using template matching techniques. 44 subjects‟ raw ECG data were downloaded from Physionet website repository. We used a template matching technique for the authentication process and Linear SVM algorithm for the classification task. The accuracy rate was 97.2% for the authentication process and 98.6% for the classification task; with false acceptance rate 1.21%.

In this paper, the modified GoogLeNet is used for ECG data classification. Using a transfer learning approach and adjustments to parts of the output layers, ECG classification was conducted and the effectiveness of convolutional neural network (CNN) designs was tested. By comparing the results that the optimized neural network and GoogLeNet both had classification accuracy about of 80% and 100%, respectively. The GoogLeNet provide the best result in term of accuracy and training time.

Photoplethysmography (PPG) and Phonocardiography (PCG) are two important non-invasive techniques for monitoring physiological parameters of cardiovascular diagnostics. The PCG signal discloses information about cardiac function through vibrations caused by the working heart. PPG measures relative blood volume changes in the blood vessels close to the skin. This paper emphasizes on simultaneous acquisition of PCG and PPG signals from the same subject with the aid of NIELVIS II+ DAQ and the signals are imported to MATLAB for further processing. Heart rate is extracted from both the signals which are found to be distinctive. This analytical approach of processing these signals can abet for analysis of Heart rate variability (HRV) which is widely used for quantifying neural cardiac control and low variability is particularly predictive of death in patients after myocardial infarction.
CLASSIFICATION OF ECG ARRHYTHMIAS USING /DISCRETE WAVELET TRANSFORM AND NEURA...IJCSEA Journal
Automatic recognition of cardiac arrhythmias is important for diagnosis of cardiac abnormalies. Several algorithms have been proposed to classify ECG arrhythmias; however, they cannot perform very well. Therefore, in this paper, an expert system for ElectroCardioGram (ECG) arrhythmia classification is proposed. Discrete wavelet transform is used for processing ECG recordings, and extracting some features, and the Multi-Layer Perceptron (MLP) neural network performs the classification task. Two types of arrhythmias can be detected by the proposed system. Some recordings of the MIT-BIH arrhythmias database have been used for training and testing our neural network based classifier. The simulation results show that the classification accuracy of our algorithm is 96.5% using 10 files including normal and two arrhythmias.
WAVELET SCATTERING TRANSFORM FOR ECG CARDIOVASCULAR DISEASE CLASSIFICATIONijaia
Classifying the ECG dataset is the main technique for diagnosing heart disease. However, the focus of this
field is increasingly on prediction, with a growing dependence on machine learning techniques. This study
aimed to enhance the accuracy of cardiovascular disease classification using data from the PhysioNet
database by employing machine learning (ML). The study proposed several multi-class classification
models that accurately identify patterns within three classes: heart failure rhythm (HFR), normal heart
rhythm (NHR), and arrhythmia (ARR). This was accomplished by utilizing a database containing 162 ECG
signals. The study employed a variety of techniques, including frequency-time domain analysis, spectral
features, and wavelet scattering, to extract features and capture unique characteristics from the ECG
dataset. The SVM model produced a training accuracy of 97.1% and a testing accuracy of 92%. This work
provides a reliable, effective, and human error-free diagnostic tool for identifying heart disease.

A Joint QRS Detection and Data Compression Scheme for Wearable Sensorsecgpapers
Abstract—This paper presents a novel electrocardiogram (ECG)
processing technique for joint data compression and QRS detection
in awireless wearable sensor. The proposed algorithm is aimed
at lowering the average complexity per task by sharing the computational
load among multiple essential signal-processing tasks
needed for wearable devices. The compression algorithm, which is
based on an adaptive linear data prediction scheme, achieves a lossless
bit compression ratio of 2.286x. The QRS detection algorithm
achieves a sensitivity (Se) of 99.64% and positive prediction (+P)
of 99.81% when tested with the MIT/BIH Arrhythmia database.
Lower overall complexity and good performance renders the proposed
technique suitable for wearable/ambulatory ECG devices.

The data acquisition unit used is the user pc/ laptop with MATLAB. Using very specific image processing techniques the critical intelligence from the captured image is extracted. From this processed image any sort of abnormal conditions is determined which is informed to the corresponding doctor via text message. Simultaneously the processed image is sent to the doctor mail by using specific TCP/IP protocol.
Electrocardiograph signal recognition using wavelet transform based on optim...IJECEIAES
Due to the growing number of cardiac patients, an automatic detection that detects various heart abnormalities has been developed to relieve and share physicians’ workload. Many of the depolarization of ventricles complex waves (QRS) detection algorithms with multiple properties have recently been presented; nevertheless, real-time implementations in low-cost systems remain a challenge due to limited hardware resources. The proposed algorithm finds a solution for the delay in processing by minimizing the input vector’s dimension and, as a result, the classifier’s complexity. In this paper, the wavelet transform is employed for feature extraction. The optimized neural network is used for classification with 8-classes for the electrocardiogram (ECG) signal this data is taken from two ECG signals (ST-T and MIT-BIH database). The wavelet transform coefficients are used for the artificial neural network’s training process and optimized by using the invasive weed optimization (IWO) algorithm. The suggested system has a sensitivity of over 70%, a specificity of over 94%, a positive predictive of over 65%, a negative predictive of more than 93%, and a classification accuracy of more than 80%. The performance of the classifier improves when the number of neurons in the hidden layer is increased.
Heart rate detection using hilbert transformeSAT Journals
Abstract The electrocardiogram (ECG) is a well known method that can be used to measure Heart Rate Variability (HRV). This paper describes a procedure for processing electrocardiogram signals (ECG) to detect Heart Rate Variability (HRV). In recent years, there have been wide-ranging studies on Heart rate variability in ECG signals and analysis of Respiratory Sinus Arrhythmia (RSA). Normally the Heart rate variability is studied based on cycle length variability, heart period variability, RR variability and RR interval tachogram. The HRV provides information about the sympathetic-parasympathetic autonomic stability and consequently about the risk of unpredicted cardiac death. The heart beats in ECG signal are detected by detecting R-Peaks in ECG signals and used to determine useful information about the various cardiac abnormalities. The temporal locations of the R-wave are identified as the locations of the QRS complexes. In the presence of poor signal-to-noise ratios or pathological signals and wrong placement of ECG electrodes, the QRS complex may be missed or falsely detected and may lead to poor results in calculating heart beat in turn inter-beat intervals. We have studied the effects of number of common elements of QRS detection methods using MIT/BIH arrhythmia database and devised a simple and effective method. In this method, first the ECG signal is preprocessed using band-pass filter; later the Hilbert Transform is applied on filtered ECG signal to enhance the presence of QRS complexes, to detect R-Peaks by setting a threshold and finally the RR-intervals are calculated to determine Heart Rate. We have implemented our method using MATLAB on ECG signal which is obtained from MIT/BIH arrhythmia database. Our MATLAB implementation results in the detection of QRS complexes in ECG signal, locate the R-Peaks, computes Heart Rate (HR) by calculating RR-internal and plotting of HR signal to show the information about HRV. Index Terms: ECG, QRS complex, R-Peaks, HRV, Heart Rate signal, RSA, Hilbert Transform, Arrhythmia, MIT/BIH, MATLAB and Lynn’s filters

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

make this interpretation easier for non-trained people and the system could detect the disease
with high levels of accuracy because many people who died cause of heart disease showed no
outward symptoms. This research is used by the other health care professionals including
physicians, nurses, therapists and technicians to bring together knowledge from many
technical sources to develop new procedures, or to solve clinical problems. The compression
algorithm is used to transmit the ECG signal to hospital server efficiently. The compression
minimizes the data amount during the compression. The Cardiac abnormalities can be
identified fastly and efficiently using ECG signals. In this project, it is proposed
to perform real-time classification of Cardiac Vascular Disease (CVD). Here the features
selection for the ECG is done using feature extraction technique. The methods presented here
are divided into three pieces of work. Firstly, procedures to identify and annotate of ECG
signal for Normal, Bradycardia Arrhythmia, Tachycardia Arrhythmia and Ischemia
characteristic. Secondly, a strategy is presented for extracting the features vector for each
sample of selected heart disease using an algorithm that exploits the coefficient derived from
Discrete Wavelet Transform. Lastly, this part presented the procedures of classification
process using Adaptive Neural Fuzzy Inference System modeling.
II.RELATED WORKS
There are many techniques introduced by the researches to overcome the heart problems
in day-today-life. The holter monitor system which records ECG signal continuously in
ambulatory condition for a sizable time and system transmit the recorded data to hospital
when the recorded period is completed.
The ECG analysis technique required the feature extraction and classifier stage. Before
feature extraction the noise is removed from the ECG signal. For noise reduction many
reduction techniques are proposed by different researchers. An approach to Cardiac
Arrhythmia Analysis using Hidden Markov Models. This technique classified by detecting
and analyzing QRS complex and determining the R-R intervals to determine the ventricular
arrhythmias.
DWT-based feature extraction technique yields superior performance. ECG analysis
using wavelet transform method can distinguish the between the QRS wave and P, T wave.
This technique also can distinguish noise, baseline drift and artifacts. The two morphological
feature extraction methods which are higher-order statistics and hermite basis functions.
A new approach to feature extraction which is Karhunen Lo’eve Transform (KLT)
which is an attractive and powerful approach to the feature-extraction and shape
representation process. It has the solution if the probability densities of population of pattern
vectors of a problem domain are unknown. In designing an ECG classifier based on Neural
Network (NN) , the normal procedure is to firstly train the network by presenting it with
training data that is representative of the unknown data it is likely to experience during the
classification process.
The Neuro-Fuzzy approach to the recognition and classification of the heart rhythms on
the basis of ECG waveforms. It uses the new approach of heart beat recognition. This project
is the resolution for the problem of less sensitivity to the morphological variation of the ECG.

III.METHODOLOGY
This system provides useful technique for fast identification and treatment of the heart
disease. This paper provides the detection of cardiovascular disease in ECG signal by the
help of health care centers in rural areas. In figure 1 the signal is recorded from the patient’s
body and it is monitor by the physicians. The signal is then classified by the physicians by
applying Neuro-Fuzzy classifier technique. This shows the result as whether the patient’s is
in the normal, mild or severe condition. If the patient’s condition is critical, then the signal is
transmitted to the hospital server by compressing the ECG signals using Huffman coding. For
the severe cases physician will provide a tablet that could maintain the heart beat as normal
for 6 hours which would help him to reach the Cardiac hospital. Then the patient can undergo
for medical treatment by the cardiologist. If the patient’s condition is mild then they are
advised to contact the cardiologist.

A.DWT Technique for Feature
Extraction
In this scope of this thesis, feature extraction was conducted by applying wavelet
analysis techniques to patient data, thus providing ECG characteristic point detection
capabilities. Since most recently published detectors are based on standard database
libraries and limited wave detection, this application is an attempt to expand the horizons
of current research efforts. The procedures of DWT implementation is describe as follow in

Figure 2: Feature Extraction Techniques
The general wavelet decomposition of DWT procedure involves three steps. The result
of decomposed signal will shows the important details and approximation coefficients. Which
represent the original signal. The basic version of the procedure follows the steps described
below
• Choose a wavelet types.
• Choose a wavelet name.
• Choose a level N which will compute the wavelet decomposition of the signals at
level N.
The DWT wavelet types have been chosen in this features extraction method and the
ECG signals were decomposed into time-frequency representations using single-level one-
dimensionalwavelet.The wavelet names of Daubechies wavelet filters db4 have been
choosing and the number of decomposition levels was chosen to be 5. Thus, the ECG signals
were decomposed into the details coefficients D1-D5 and one final approximation coefficient,
A5.
The results of applying the Daubechies wavelet of order 4(db4) which is more suitable
to detect changes of ECG signal is evaluated. The wavelet filter with scaling function more
closely similar to the shape of the ECG signal achieved better detection. Db wavelet family is
similar in shape to ECG signal and their energy spectrums are concentrated around low
frequencies the signal is approximated by omitting the signals high frequency components.In
this study, from the original intervals of ECG signal, five standard measures parameters used
are used. A signal of 75 discrete data was selected as considered ECG signals data. For each
ECG signals, the detail wavelet coefficients of fourth level (75 coefficients) were computed.
In order to reduce the dimensionality of feature vectors, statistics over the set of the
wavelet coefficients were used. The following statistical features were used to represent the
time-frequency distribution of the ECG signals:

Heart Disease
The classification was performed using the ANFIS in Fuzzy Logic Toolbox. ANFIS
were trained with the back propagation gradient decent method in combination with the least
squares method. The block of featured processed in ANFIS were shown in Figure 4. ANFIS
required a predefined network structuionre and its membership function as well as other
parameters can be trained during the learning process. The system is first designed using
Sugeno Fuzzy Inference System (FIS).

Figure 4: Block Diagram of Heart Disease Classification through ANFIS
There are two types of FIS namely Grid Partition and Subtractive Clustering. The
ANFIS Grid Partition was adopted in this study because this system required the number of
membership functions for each input. This system uses the gbell shaped membership
function to characterize the fuzzy set input and Sugeno output membership functions are
linear types. In the layer 1, there are five nodes have been used for each input dimension Xi
where i=1,2,..d and d is the member of input dimensions. The ANFIS which constructs a
FIS, whose membership function parameters are tuned using a backpropagation algorithm
in combination with a least squares type of method, will allows fuzzy systems to learn from
the data that they are modeling. The FIS of heart disease classification. Based on five input-
one output systems, the five variables were used which are Energy, Maximum, Minimum,
Mean and Standard Deviation of DWT coefficients and the output class either Normal,
Bradycardia Arrhymia, Tachycardia Arrhythmia or Ischemia is taken as the output variable.
The input parameters are represented by fuzzy set or linguistic Variables.
C. Lossless Compression: Huffman Coding
The delta coding and the lossless compression algorithm are adapted after the skeleton
method. The delta coding is calculated with difference with the previous number (yi = xi −
xi−1 ). stores the changes instead of the absolute values to reduce the number of bit. The
Huffman coding is selected because it provides minimum encoding cost when the original
data has the unique distribution [5]. According to the Huffman Coding scheme, the most
frequently occurring values have the shortest bit code length, and the rarely occurring data
have the longest bit code length. After the skeleton step, the input data have Gaussian
distribution, which is more than 50% of the data are located near the zero. Thus, these high
frequently occurring data can be transformed with the short length of code by the Huffman
coding.
The modified Huffman coding method transforms the sample-oriented format into the
4-bitwordoriented stream. So, it can obtain the unified data format for the efficient memory
access, although the variable sample resolution is provided. When decoding the Huffman
code, the bit stream is decoded into the 4-bit-word. The first bit is picked up and compared

with the Huffman table, and the original value is reconstructed from the remaining encoded
data. The average CR of the Huffman coding is approximately 2:1 without the compression
error rate.
IV.RESULT AND PERFORMANCE ANALYSIS
In this study, training and test sets were formed by 52 data train the samples. The 27
data samples were used for training and 25 data samples were for testing. The training dataset
was used to train the ANFIS, whereas the testing dataset was used to verify the accuracy and
the effectiveness of the trained ANFIS model for the detection of heart disease patients.
Table 1: Statistic of correct and incorrect Heart Disease Classification
Table 1 and Figure5 show the correct classified and misclassified data samples of heart
disease for each class.The MIT-BIH Arrhythmia Database is used to evaluate the
performance. The sampling rate and the resolution are 360 samples/s and 12 bits,
respectively. In addition, the Gaussian white noise source is injected from −10 to 20 dB SNR
for the noise stress test. The test vector is produced by injection of the noise source with
MIT-BIH record 100. The performances of compression coding are evaluated by the CR and
the compression error rate of the percentage root mean square difference (PRD).

V. CONCLUSION
This paper indicate that by using DWT and ANFIS, the classification of Normal,
Bardycardia Arrhythmia, Tachycardia Arrhythmia and Ischemia signals can be classified;
therefore the primary objective of this study isachieved. The simulation results show
that the class of heart disease is well predicted using DWT and ANFIS system and the system
working well since it achieve the 97.68% of classification accuracy rate. This result indicates
that it has some potential and had been found to be successful in heart disease detection. The
proposed QLV delineate the ECG signal, and it supports both the flows to achieve better
performance with low computation complexity. By applying the QLV, the overall CR
improves while maintaining the small compression error rate, and high-accuracy performance
can achieve at the segmentation and the R-peak detection stage. The performance is evaluated
by using the MIT/BIH Arrhythmia Database, and the noise robust test is also performed for
the reliability of the algorithm. The average CR is 16.9:1 with 0.641% PRD value, and the
encoding rate is 6.4 kbps. The accuracy performance of the R-peak detection is 100% without
noise and 97.5% at the worst case with −10 dB SNR noise.
