INTRODUCTION
• Electrocardiogram, abbreviated as ECG is a test that measures the electrical
activity of the heart.
• With each heartbeat, an electrical impulse travels through the heart which
causes the heart muscles to contract and relax pumping blood in and out of the
heart.
• Electrical signals are produced by the polarisation and depolarisation i.e., by
contractions of the cardiac tissue which drive electrical currents and create
different potentials throughout the body.
• An ECG graph gives vital information about the proper functioning of the
heart and its abnormalities.

PROBLEM DEFINITION
• People with cardiovascular diseases are at high risks of possible
cardiovascular events and are prone to abnormal heart activities.It is therefore
necessary to monitor their heart activities under sensitive situations.
• Conventional ECG systems are tethered and not easily portable.
• Also, traditionally, ECG recordings are performed by doctors in hospitals and
clinics and are not available to record one’s heart activity while being in
various environments and engaged in various activities.
• Hence it becomes necessary to address the problems of the conventional ECG
system and make it convenient for cardiovascular patients to record their heart
activity with ease and without a specialist’s intervention.

OBJECTIVES OFTHE PROJECT
The device should be:
 A non-bulky system and would be portable
 Is very easily integrated with the finger tip sensor and the display
 Does not require any sort of patient preparation
 Is usable by the patient working in any environment and undergoing any
activity

FINGERTIP ECG ACQUISITION SYSTEM
Pulse sensor detects the
heartbeat and converts
it into Electrical Signal
These electrical signals
are then sent to the
Arduino for processing.
What happens in the
Arduino: Filtering, Peak
detection, heartbeat
waveform
segmentation and
amplification
The resultant graph and
other data is displayed

PROPOSED SOLUTION
FINGERTIP ECG ACQUISITION SYSTEM 9/28/2023
Fig. [2] : Circuit Diagram
EXPLANATION OF CODE
• There is a threshold condition to avoid high frequency and unwanted noise.
• The variables are declared to receive signals from the heart sensor. The inbuilt
Arduino LED blinks every time it receives a pulse.
• This sensor/device works on the principle of generation of an electrical signal
at the fingertip, which is detected by the sensors. At every contraction the
electrical signal surpasses a threshold value, so that the heart sensor switches
on and the pulse can be detected.
• The pulse value is detected and is displayed on the Serial monitor with certain
intervals. The QRS curve which is expected, is displayed with Time (in ms) on
X-axis and Voltage (mV) on Y-axis. Thus, the graph output can be obtained.
• The software used are Arduino IDE. Arduino IDE uses Embedded C language
code to pick up the electrical signals from the sensors and displays the PQRS
curve of the heart.

OUTPUT
• By using this system, one’s heart rate can be measured through fingertip.
• The system determines the heart beat rate per minute and displays the ECG
waveform on the computer screen.
• It can be interfaced to get the output on a mobile screen as well.

ADVANTAGES OF PROPOSED
SOLUTION
• Eliminates the use of Conducting gel(The gel is used to bind the electrodes to the
chest region in the human body) - Dry sensors are used in a fingertip ECG system
which is completely versatile and very easy to use.
• Highly portable - It is a small device, unlike the conventional bulky ECG machine
used in labs and hospitals.
FINGERTIP ECG ACQUISITION SYSTEM 9/28/2023
ADVANTAGES OF PROPOSED
SOLUTION
• Easily affordable - Use of small electronic components and the seamless
combination of Hardware and Software makes our proposed solution an affordable
one.
• Can also be considered as the small chunk of an integrated system - The use of
state-of-the-art Microcontrollers prove to be efficient in achieving a seamless
addition of different kinds of sensors.
• The SNR here is high compared to the PPG sensors used in smartwatches.

BUDGET
• An estimate of the total budget is about One thousand Rupees i.e., 1000INR
• The split-up for the above is as follows:
Arduino Development Board with Connector: 500 INR
Heart rate sensor: 200 INR
Electronic components such as LCD display, jumpers and others: 250 INR

FUTURE DEVELOPMENT
• Normal ECG database of all age categories can be taken in memory
and a buzzer can be interfaced to the Arduino.
• The displayed ECG waveform on the PC can be compared to the
database.
• If there is a difference between the two, then the buzzer will sound
indicating that the ECG waveform is not normal.
• This system can also be integrated with other medical systems thereby
increasing the functionality of the project.

  • 18. EXPLANATION OF CODE • There is a threshold condition to avoid high frequency and unwanted noise. • The variables are declared to receive signals from the heart sensor. The inbuilt Arduino LED blinks every time it receives a pulse. • This sensor/device works on the principle of generation of an electrical signal at the fingertip, which is detected by the sensors. At every contraction the electrical signal surpasses a threshold value, so that the heart sensor switches on and the pulse can be detected. • The pulse value is detected and is displayed on the Serial monitor with certain intervals. The QRS curve which is expected, is displayed with Time (in ms) on X-axis and Voltage (mV) on Y-axis. Thus, the graph output can be obtained. • The software used are Arduino IDE. Arduino IDE uses Embedded C language code to pick up the electrical signals from the sensors and displays the PQRS curve of the heart. 9/28/2023 FINGERTIP ECG ACQUISITION SYSTEM
  • 20. OUTPUT • By using this system, one’s heart rate can be measured through fingertip. • The system determines the heart beat rate per minute and displays the ECG waveform on the computer screen. • It can be interfaced to get the output on a mobile screen as well. 9/28/2023 FINGERTIP ECG ACQUSITION SYSTEM Fig. : Trial Output Run 1

  • 26. BUDGET • An estimate of the total budget is about One thousand Rupees i.e., 1000INR • The split-up for the above is as follows: Arduino Development Board with Connector: 500 INR Heart rate sensor: 200 INR Electronic components such as LCD display, jumpers and others: 250 INR FINGERTIP ECG ACQUISITION SYSTEM 9/28/2023
  • 27. FUTURE DEVELOPMENT • Normal ECG database of all age categories can be taken in memory and a buzzer can be interfaced to the Arduino. • The displayed ECG waveform on the PC can be compared to the database. • If there is a difference between the two, then the buzzer will sound indicating that the ECG waveform is not normal. • This system can also be integrated with other medical systems thereby increasing the functionality of the project. 9/28/2023 Fingertip ECG System
