Abstract: In general, techniques and systems for detecting acoustic signals and generating phonocardiograms are described. In one example, a system may include an acoustic sensor configured to detect an acoustic signal from a heart of a patient. The system may also include a sensing module configured to detect an electrical signal from the heart of the patient via two or more electrodes and at least one processor configured to generate a composite phonocardiogram based the acoustic signal and the electrical signal detected over a plurality of cardiac cycles of the heart, wherein the composite phonocardiogram is generated for a representative cardiac cycle. The system may be provided in a single device or multiple devices configured to transmit information between the devices.

Abstract: An electronic stethoscope includes a housing configured for hand-held manipulation, a transducer supported by the housing and configured to sense auscultation signals at a first location, and a headset coupled to the housing and configured to deliver audio corresponding to the auscultation signals through earpieces on the headset. The electronic stethoscope further includes a processor disposed in the housing and configured to convert the auscultation signals to first digital signals representative of the auscultation signals and to wirelessly transmit the first digital signals from the electronic stethoscope via a secure digital network to a second location such that the audio corresponding to the auscultation signals is provided to headsets of one or more additional electronic stethoscopes at the second location in substantial real time with the sensing of the auscultation sounds at the first location.
