Abstract
Systems and methods are provided to detect a multi-domain ECG waveform and display one or more cardiac electrophysiological markers. Electrical impulses are detected between at least one pair of electrodes adapted to be located near a beating heart and are converted to an ECG waveform. The ECG waveform for at least one heartbeat is received from the detector, the ECG waveform is converted to a frequency domain waveform, the frequency domain waveform is separated into two or more different frequency domain waveforms using two or more different bandpass filters, and the two or more different frequency domain waveforms are converted into two or more different time domain waveforms. The two or more different time domain waveforms are displayed in the same time domain plot as the ECG waveform and one or more cardiac electrophysiological markers are displayed along the x-axis of the two or more different time domain waveforms.
