Claim:
1. A noninvasive electrocardiography (ECG) system for detecting one or more subwaveforms within the Q, R, S, and T waveforms or in an interval between the Q, R, S, and T waveforms and displaying at least one conduction timing value for at least one subwaveform of the one or more subwaveforms, comprising: two or more electrodes adapted to be located near a beating heart of a patient and attached to the skin of the patient that receive electrical impulses from the beating heart; a detector that detects the electrical impulses from at least one pair of electrodes of the two or more electrodes and converts the electrical impulses to an ECG waveform for each heartbeat of the beating heart; a signal processor that receives the ECG waveform for each heartbeat from the detector, detects one or more subwaveforms within Q, R, S, and T waveforms of the ECG waveform or in an interval between the Q, R, S, and T waveforms that represent the depolarization or repolarization of anatomically distinct layers of the ventricles of the beating heart, and calculates a conduction timing value for each of the one or more subwaveforms for each electrode of the two or more electrodes for each heartbeat of the beating heart; and a display device that displays at least one conduction timing value for at least one subwaveform of the one or more subwaveforms for each electrode of the two or more electrodes for at least one heartbeat of the beating heart.
