Portable Electro Cardiography Simulator
Project Area of Specialization Biomedical EngineeringProject SummaryAccording to the World Health Organization (WHO), cardiovascular diseases have affected the lives of around 17.7 million people every year accounting for 31% of all deaths globally.
Electrocardiography (ECG) is a process to record electrical signals in human heart. ECGs are carried out to diagnose heart problems and to monitor heart’s health. A normal heart beats 60 to 100 times per minute in adults with a uniformity and regularity. Other types of waveforms are considered abnormal. Most common types of abnormal ECG waveforms produced by a human heart are tachycardia, bradycardia and atrial fibrillation
There are three main components to an ECG: the P wave which represents the depolarization of the atria; the QRS complex, which represents the depolarization of the ventricles; and the T wave,which represents the repolarization of the ventricles.
About 10% of the ECG interpretation (all of them were abnormal) by machine were wrong, which would have led to misdiagnosis. Therefore, it is extremely important for ECG machines to get checked with a testing device before interfacing it with humans directly.
An ECG simulator is just like an artificial heart and is capable of generating different heart waves through electrical signals .in order to validate ECG monitor’s performance it is essential to test it through ECG simulator.
Our project introduces such a tool that is capable of generating required test signals with increased functionality and flexibility compared to existing available test tool such as ProSim by Fluke Biomedical USA. A key benefit is that this simulator allows user-interaction via graphical user interface (GUI) while, at the same time, signals are accessible through a hardware output.
The goal of our project is to develop a portable ECG simulator, needed for testing of ECG machines. It should be able to generate analog signals of heart waves and to reproduce the amplitude and frequency accuracy of the standardized training databases. By including normal sinus rhythms, different arrhythmia types and test waveforms, the proposed device becomes really efficient both for medical equipment maintenance and educational purposes.
Project ObjectivesIt is designed to check the malfunctioning of ECG machines. It is a must have tool to calibrate ECG machines so that proper Diagnosis can be done . It can Also be used for Educational purposes and research work.
Project Implementation MethodECG simulator will take some parameters as input, which can be selected by
the user using the touchscreen display. Once the combination of these parameters is
selected and entered, the microcontroller starts producing the ECG waveform which
can be observed on the screen and obtained from the output electrodes.
In order to produce a normal sinus rhythm (fig 1.1) the microcontroller will
produce a single cycle, with respect to the parameters like amplitude and age group.
Then this cycle will be repeated in a loop, whose frequency will be defined by the
entered heart rate.
While on the other hand some arrhythmic waveforms are completely random
like ventricular fibrillation (fig 1.2). The microcontroller will produce such
waveforms from a small number of readings (enough to be displayed on a single
screen) from MIT-BIH Arrhythmia Database, and play the sequence in a loop.
The microcontroller will keep on producing the waveform until an interrupt
is triggered like a stop/back button on the touch display.
It can check the performance of ECG machines which can be beneficial to diagnose diseases properly. It can also be used to simulate Artificial heart waves so that researchers and students can get benefit from it
Technical Details of Final DeliverableIt is a portable Electro cardiography simulator that can be used to generate artifical heart waves. it comprises both of software for signal generation and a dedicated hardware
circuit board enclosed in 3D printed case for signal output.
