MATLAB assisted analog ECG system simulator

Abstract EN

ECG machines play an important role in the primary diagnosis and survival analysis of heart diseases.

Electrocardiography has had a profound influence on the practice of medicine.

Large amount of ECG machines are the traditional analog ones, here simulation of an analog ECG is considered trying to get closer look at its design and aiming to better understanding and possible circuit modifications.

This simulator is built using two major sections, the first one is used to make the electrodes signal (stander limb leads connection) suitable to be used by MATLAB, formed from an instrumentation amplifier and a data acquisition card.

The second part is the Simscape MATLAB library performing the signal filtering and amplifying.

The chosen ECG circuitry is got from an ECG training kit, but it can be modified as needed.

This simulator shows same ECG signal as got by the kit and gives an easy means to modify the design and note the signal at different stages of the simulator.
