ECG Signal Simulation with MATLAB Implementation

ECG signal simulation is a method for replicating electrocardiogram waveforms. This approach utilizes the superposition of multiple triangular and sinusoidal waves to generate realistic ECG signal patterns. Through this simulation technique, researchers can better understand and analyze the characteristics and behavior of cardiac electrical activity. The implementation typically involves generating base waveforms using trigonometric functions, adjusting their amplitudes and frequencies to match typical ECG components (P waves, QRS complexes, T waves), and combining them through weighted summation. ECG signals represent crucial biological data that significantly aids in cardiac disease diagnosis and heart health monitoring. Therefore, ECG signal simulation serves as a valuable and meaningful technological approach for medical research and educational purposes, often implemented using MATLAB's signal processing toolbox functions like sawtooth() for triangular waves and sin() for sinusoidal components with precise timing control.
