Abstract
An ECG system measures and annotates a subdivision of the P wave of the ECG waveform from harmonic waveforms. Electrical impulses are received from a beating heart. The electrical impulses are converted to an ECG waveform. The ECG waveform is converted to a frequency domain waveform, which, in turn, is separated into two or more different frequency domain waveforms, which, in turn, are converted into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms. The plurality of subwaveforms and discontinuity points are compared to a database of subwaveforms and discontinuity points for normal and abnormal patients. Starting and ending discontinuity points are identified for a subdivision of the P wave of the ECG waveform and an APD is calculated for the subdivision. The ECG waveform is displayed along with a location of the P wave subdivision on the ECG waveform and the calculated APD.
