Claim 3:
4. A method for displaying subwaveforms of the ST segment of an electrocardiography (ECG) waveform during measurement of the ECG waveform, comprising:
receiving electrical impulses from a beating heart using two or more electrodes;
detecting the electrical impulses from at least one pair of electrodes of the two or more electrodes and converting the electrical impulses to an ECG waveform for each heartbeat of the beating heart using a detector;
receiving the ECG waveform for at least one heartbeat from the detector, converting the ECG waveform to a frequency domain waveform, separating the frequency domain waveform into two or more different frequency domain waveforms, and converting the two or more different frequency domain waveforms into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms of the ECG waveform using a processor;
comparing the plurality of subwaveforms and discontinuity points to a database of subwaveforms and discontinuity points for cardiac electrophysiological signals of ECG waveforms for a plurality of known and normal and abnormal patients or to a set of rules developed from the database using the processor;
identifying an ST segment and one or more ST subwaveforms within the ST segment from the plurality of subwaveforms and discontinuity points based on the comparison using the processor; and
displaying the ECG waveform with the one or more ST subwaveforms within the ST segment for the at least one heartbeat of the beating heart using the display device.
