Abstract
Systems and methods are provided to display discrete conduction timing values of layers of the ventricles. Electrical impulses are detected using two or more electrodes placed proximate to a beating heart and are converted to an ECG waveform for each heartbeat of the beating heart. One or more subwaveforms within Q, R, S, and T waveforms of the ECG waveform for each heartbeat or in an interval between the Q, R, S, and T waveforms are detected that represent the depolarization or repolarization of anatomically distinct layers of the ventricles of the beating heart. A conduction timing value is calculated for each of the one or more subwaveforms for each electrode of the two or more electrodes for each heartbeat of the beating heart. At least one conduction timing value is displayed for at least one subwaveform for each electrode for at least one heartbeat of the beating heart.
