ABSTRACT:
The invention is directed to an implantable medical device (IMD) that includes an accelerometer. The accelerometer is used to detect heart tones associated with blood flow through one or more cardiac valves. In particular, the IMD measures durations of the heart tones detected by the accelerometer, and uses the measured durations to identify deterioration of the heart. In this manner, the IMD facilitates early detection of cardiac deterioration so that proper therapy can be delivered to the patient to remedy and combat such deterioration.
