Abstract

See full text

An acoustic sensor is located in association with a patient's heart to detect abnormal heart sounds and a processor isolates abnormal heart sounds therefrom. The characteristics of these heart sounds are monitored while adjustments are made to the timing of pacing pulses to achieve a better heart function through pacing therapy. Particular adaption to cardiomyopathy is shown.
