This paper presents a simplified and effective method for determining heart rate from Electrocardiogram (ECG) signals using MATLAB. It focuses on advanced signal denoising techniques like Empirical Mode Decomposition (EMD), Notch filters, and wavelet transforms. The methodology improves signal quality by removing Power Line Interference (PLI) and Baseline Wander (BW), allowing accurate detection of R-peaks and heart rate. The algorithm’s performance is validated using datasets from the MIT/BIH database, and results are benchmarked against the Pan-Tompkins algorithm. The effectiveness of classification is also evaluated using discrete wavelet transform (DWT) based feature extraction.
