Electronic acoustic stethoscope with ECG

A noninvasive system for detecting and processing phonocardiogram (PCG) and electrocardiography (ECG) waveforms, comprising:

• an electronic acoustic stethoscope that includes an earpiece and a chestpiece, wherein the chestpiece includes an acoustic transducer, at least four electrodes, a wireless communication device, and at least one processor, wherein the acoustic transducer is adapted to contact skin of a patient, measure heart sounds of the patient, and send the heart sounds to the earpiece and the at least one processor is adapted to create a PCG waveform of the heart sounds, wherein the at least four electrodes are adapted to contact the skin of the patient and measure heart electrical signals of the patient and the at least one processor is adapted to create an ECG waveform of the heart electrical signals, wherein the wireless communication device is adapted to transmit the PCG waveform and the ECG waveform;
• and
• a server computer that is adapted to receive the PCG waveform and the ECG waveform from the wireless communication device, process the PCG waveform for additional PCG information, process the ECG waveform for additional ECG information, and provide access to the additional PCG information and additional ECG information to at least one device adapted to be a client device, wherein the server computer further includes a signal processor that receives the ECG waveform, individually detects five ECG subwaveforms within the PR interval of the ECG waveform that represent depolarization of a sinoatrial node (SAN), an atria (right atrium (RA) and left atrium (LA)), an atrioventricular node (AVN), a bundle of His (HIS), and bundle branches (BB), respectively, using five predetermined frequency ranges experimentally found for the SAN, the RA and LA, the AVN, the HIS, 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.
