Resource Overview
Develop a MATLAB program to plot ECG signals, locate R-wave positions (provided in the dataset), calculate cardiac cycles, and generate a heart rate versus time curve to distinguish between normal and abnormal heart rhythms. Includes implementation details for signal processing and feature extraction.
Detailed Documentation
Develop a MATLAB program to plot ECG signals, identify R-wave positions (with R-wave locations provided in the dataset), calculate cardiac cycles, and plot heart rate variation over time to analyze differences between normal and abnormal cardiac rhythms. The implementation involves using MATLAB's plotting functions (like plot()) for visualization, array operations to compute intervals between consecutive R-waves, and time-series analysis for heart rate calculation. Additionally, implement filtering techniques (such as bandpass filtering using filter() or designfilt() functions) to preprocess the ECG signal and extract clinically significant features like ST-segment changes or QRS complex morphology. This enables deeper investigation of ECG characteristics and cardiac condition assessment through spectral analysis and waveform pattern recognition algorithms.
