Detect R peaks of the QRS complex in a raw ECG record, based on the algorithm proposed by Bahoura, Hassani & Hubin (1997)
bahoura(ecg, fs)
ecg |
The input single-channel input vector (raw ECG) |
fs |
The frequency in Hz with which the ecg was sampled |
This function attempts to detect ECG fiducial points in a single-channel electrocardiogram signal using the algorithm proposed by Bahoura, Hassani & Hubin (1997), which is a simplified version of the method proposed by Li, Zheng & Tai (1995).
Numeric array containing the indices (sample numbers) at which the fiducial R-peaks were found
