pantompkins¶
Algorithm for R-wave detection in ECG signals.
Syntax¶
function varargout = pantompkins(ecg, fs, varargin)
Description¶
TK = PANTOMPKINS(ECG, FS) Detects R-waves in ECG signals sampled at FS Hz using the Pan-Tompkins algorithm. This method applies bandpass filtering, derivative calculation, squaring, and integration to enhance R-wave peaks. TK is a column vector containing the R-wave occurrence times in seconds.
TK = PANTOMPKINS(..., Name, Value) allows specifying additional options using name-value pairs. - 'BandpassFreq' - Two-element vector [low, high] for bandpass filter cutoff frequencies in Hz. Default: [5, 12] - 'WindowSize' - Integration window size in seconds. Default: 0.15 - 'MinPeakDistance' - Minimum distance between peaks in seconds. Default: 0.5 - 'SnapTopeakWindowSize' - Window size in samples for peak refinement. Default: 20
