Abstract

ABSTRACT OF THE DISCLOSURE
A synchronous telemetry system and method for multiplexed telemetry of analog and digital information from a pacemaker or other implantable medical device. Telemetry sync pulses are generated at a 1 kHz rate, and pulse-position modulation is employed for generating an analog data pulse and a digital data pulse relative to the same sync pulse and displaced therefrom by different intervals respectively corresponding to the instantaneous value of an analog input signal and the instantaneous state of a digital input signal. In addition to multiplexing of analog and digital information in a composite bit, multiplexing is provided for dual-channel analog operation.
