Abstract :
In ECG signals processing it is sometimes necessary to determine the timing of different ECG segments in real time, i.e. in the shortest time after they appeared in the signal. A typical example is P-wave synchronized pacing (heart stimulation synchronized with the P-wave). We used multistage methodology enabled by wavelet transform to delineate the ECG signal and develop a sensitive (98.5%) and reliable P-wave detector.
