ECG Rhythm abnormality for undergraduates
The rhythm is best analyzed by looking at a rhythm strip.
On a 12 lead ECG this is usually a 10 second recording from Lead II.
Confirm or corroborate any findings in this lead by checking the other leads.
A longer rhythm strip, recorded perhaps recorded at a slower speed, may be helpful.

This document proposes a policy-based runtime verification framework for hypertension monitoring using electrocardiogram (ECG) sensing. Key aspects include:
1) A decision tree model is implemented using timed ECG features to extract patterns/policies related to hypertension.
2) The extracted ECG policies are formally specified as timed automata to synthesize a runtime verification monitor.
3) The monitor continuously verifies the ECG policies and provides a verdict on whether hypertension is present or not based on ECG events.
The framework aims to provide explainable, non-invasive hypertension monitoring using a formal methods-based approach.

Basics of Electrophysiologic study, part 1 (2020)
An electrophysiologic study involves inserting electrode catheters into the heart to record electrical activity and induce arrhythmias. The document discusses:
1. The procedure involves placing catheters in the heart to record electrograms from the atria, His bundle, ventricles and coronary sinus.
2. The aims are diagnostic to evaluate arrhythmias and bradycardias, and therapeutic for ablation of arrhythmias.
3. Key measurements taken include intervals between P waves, His bundle activation and QRS complex to identify conduction abnormalities.
4. Tracings are analyzed to determine the rhythm, sequence of activation, effects of pacing, and identify arrhythmia mechanisms like accessory pathways

Classification and Detection of ECG-signals using Artificial Neural Networks
Electrocardiogram (ECG), a noninvasive technique is used as a primary diagnostic tool for
cardiovascular diseases. A cleaned ECG signal provides necessary information about the
electrophysiology of the heart diseases and ischemic changes that may occur. It provides
valuable information about the functional aspects of the heart and cardiovascular system. The
objective of the thesis is to automatic detection of cardiac arrhythmias in ECG signal.
Recently developed digital signal processing and pattern reorganization technique is used in
this thesis for detection of cardiac arrhythmias. The detection of cardiac arrhythmias in the
ECG signal consists of following stages: detection of QRS complex in ECG signal; feature
extraction from detected QRS complexes; classification of beats using extracted feature set
from QRS complexes. In turn automatic classification of heartbeats represents the automatic
detection of cardiac arrhythmias in ECG signal. Hence, in this thesis, we developed the
automatic algorithms for classification of heartbeats to detect cardiac arrhythmias in ECG
signal.QRS complex detection is the first step towards automatic detection of cardiac
arrhythmias in ECG signal. A novel algorithm for accurate detection of QRS complex in ECG
signal peak classification approach is used in ECG signal for determining various diseases . As
known the amplitudes and duration values of P-Q-R-S-T peaks determine the functioning of
heart of human. Therefore duration and amplitude of all peaks are found. R-R and P-R
intervals are calculated. Finally, we have obtained the necessary information for disease
detection .For detection of cardiac arrhythmias; the extracted features in the ECG signal will
be input to the classifier. The extracted features contain morphological l features of each
heartbeat in the ECG signal. This project is implemented by using MATLAB software. An
interface was created to easily select and process the signal. “.dat” format is used the for ECG
signal data. We have detected bradycardia and tachycardia. Massachusetts Institute of
Technology Beth Israel Hospital (MIT-BIH) arrhythmias database has been used for
performance analysis.

Basics of Electrocardiography, Arrhythmia & Pacemaker
This document provides an overview of electrocardiography (ECG), including basics of the cardiac conduction system, ECG leads and recording methodology, normal ECG waveforms and intervals, cardiac arrhythmias, and pacemakers. Key topics covered include the standard 12-lead ECG, techniques for interpreting rate, rhythm, intervals, and axis, common normal variants and abnormalities, types of arrhythmias including sinus, atrial, and ventricular rhythms, and basics of cardiac pacemaker function. The document serves as an educational guide for understanding ECGs and their clinical applications.
AR-based Method for ECG Classification and Patient Recognition
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.

Understand Canada health act
The Canada Health Act establishes the principles of the Canadian public health care system including public administration, comprehensiveness, universality, portability, and accessibility. The Act requires provinces and territories to comply with these principles to receive full federal health funding. The federal government sets national standards, while provinces and territories administer health plans and deliver services. Insured services under the Act include medically necessary hospital and doctor services. Provinces must provide reasonable access without financial barriers like extra-billing and user fees. The Act aims to make health care available to all eligible Canadian residents.

Ards
The document describes an acute respiratory distress syndrome (ARDS) care plan. It defines ARDS as hypoxemia and bilateral lung opacities caused by diffuse alveolar damage. The care plan outlines the clinical signs of ARDS including respiratory distress, hypoxemia on blood gases, and bilateral opacities on chest x-ray. The therapeutic goals are supportive care to prevent complications, manage hypoxemia, and decrease oxygen consumption. Monitoring parameters include daily assessment of oxygenation using the PF ratio and ventilator settings. The care plan recommends a lung protective ventilation strategy using low tidal volumes, sedation, conservative fluid management, and treating any infections.
