Design and development of microcontroller based ECG simulator

Abstract

For the training of doctors as well as for design, development and testing of automatic ECG(Electrocardiogram) machines, a subject with a known abnormality of heart is essentially required. ECG simulator is an electronic device used to simulate such subject for the above mentioned purpose. The significance of the ECG simulator is that the subject has been replaced. The simulator is a useful tool for electrocardiograph calibration and monitoring, to incorporate in educational tasks and clinical environments for early detection of faulty behavior. The device is based on a microcontroller and generates the basic ECG wave with variable beats per minute (BPM) and arrhythmia waves. These signals are fed as an input to the ECG machine. The signals can be used for testing, servicing, calibration and development of the ECG monitoring instruments.
