Abstract
A system for detecting changes in the myocardial conduction velocity and deriving control signals therefrom for controlling the delivery of electrical or other therapy to the heart or for monitoring or diagnostic purposes. The system comprises two spaced electrodes coupled to amplifiers which detect the relative arrival times of the depolarization wavefront at the electrodes, measurement circuitry for measuring the difference in arrival times to determine conduction velocity circuitry for deriving control signals for controlling operation of an implantable medical device as a function of measured conduction velocity. The particular embodiment disclosed is a cardiac pacer in which the measured conduction velocity is used to control pacing rate.
