Advanced Portable ECG Simulator: Product Development & Validation

The instrument developed by the authors is a unique system that can be used to calibrate an ECG machine. Also, it can be used for research and academic purposes, to study different arrhythmia patterns that the human heart can generate, in other words, it's a modifiable human heart. The innovativeness of the system lies in the fact, that this system generates signals at 9 different channels (i.e. 10 electrodes of ECG machine) in parallel from actual data taken from patients. Unlike conventional ECG simulators, which generates a single pattern (waveform) and feed multipliers of that into 10 different channels. The developed instrument also replicates the human heart by changing delay time between each QRS complex to change pulse rate, a feature which is also absent in conventional ECG simulators. The developed system is tested and validated with an established and certified ECG machine at Indian Institute of Medical Technology (IIMT), Kolkata.
