Publication number: 20240032875Abstract: Aspects of the present disclosure relate to a method of displaying a portion of an acoustic signal on an electronic stethoscope. The method can include receiving the acoustic signal from an acoustic sensor of the electronic stethoscope and an electrical signal from a sensing module of the electronic stethoscope. The method can include identifying a trigger point associated with the electrical signal. The method can include generating acoustic information from the acoustic signal and synchronizing the acoustic information to the trigger point for the cardiac cycle. The method can include generating a phonocardiogram as a composite phonocardiogram based on the synchronized acoustic information.
