Systems and methods for detecting ECG subwaveforms
First Claim
1. An electrocardiography (ECG) system for detecting five ECG subwaveforms within the PR interval using electrodes configured to be placed on the skin of a patient, comprising:
- two or more electrodes configured to be placed on the skin of a patient, configured to partially surround a beating heart of the patient, and configured to 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, individually detects five ECG subwaveforms within the PR interval and one or more ECG subwaveforms within the P, Q, R, S, T, U, and J waveforms of the ECG waveform or in an interval between the P, Q, R, S, T, U, and J waveforms that represent the depolarization of the sinoatrial node (SAN), the atria (right atrium (RA) and left atrium (LA)), the atrioventricular node (AVN), the bundle of His (HIS), and the bundle branches (BB), respectively, of the beating heart using five predetermined frequency ranges experimentally found for the SAN, the RA and LA, the AVN, and the BB, combines the five ECG subwaveforms, and replaces the PR interval of the ECG waveform with the combined five ECG subwaveforms, producing a processed ECG waveform that includes the combined five individual ECG subwaveforms in place of the PR interval for each heartbeat; and
a display device that displays the processed ECG waveform for each heartbeat.

Abstract
Systems and methods are provided to detect subwaveforms of an ECG waveform. Electrical impulses are detected between at least one pair of electrodes of two or more electrodes placed proximate to a beating heart and are converted to an ECG waveform for each heartbeat of the beating heart using the detector. One or more subwaveforms within P, Q, R, S, T, U, and J waveforms of the ECG waveform for each heartbeat or in an interval between the P, Q, R, S, T, U, and J waveforms that represent the depolarization or repolarization of an anatomically distinct portion of muscle tissue of the beating heart are detected using a signal processor. A processed ECG waveform that includes the one or more subwaveforms for each heartbeat is produced using the signal processor. The processed ECG waveform is received from the signal processor is displayed using a display device.
