P Wave Detection Of Ambulatory ECG

Three P wave detection algorithms were developed, implemented and tested on digitized ECG data. The experiment began with the detection of the QRS complex. The QRS complex was then used as a reference for P wave detection. The P wave was assumed to be in the range of 240 to 400 milleseconds preceding the R wave of the QRS complex. After bandpass filtering, to reduce the noise artifacts, the P wave detection algorithms were tested on this range of values. Three algorithms were tested on ambulatory ECG data from the American Heart Association. These algorithms used the P wave's first derivative as a tool for detection. The algorithms detected between 79% and 99% of the possible P waves.
