1. A therapeutic stimulation and monitoring system for a patient'"'"'s heart comprising:
- an implantable cardiac stimulation and physiological parameter monitoring device;
a programmer adapted to transceive wireless signals with the implantable device over a first channel so as to induce the implantable device to alter the therapeutic stimulation and monitored physiological parameters provided and to transmit signals indicative of the monitored physiological parameters to the programmer;
means for monitoring surface signals of the patient indicative of cardiac activity including means for transceiving wireless signals with the programmer over a second channel so as to provide the programmer with signals indicative of the surface signals of the patient and to receive signals inducing the monitoring means to alter the configuration of the surface signal provided to the programmer, wherein the first and a second channels comprise first and second time division channels.

Abstract
A programmer for implantable stimulation devices and surface ECG system in wireless communication with each other. A self-powered ECG monitor with conventional surface electrodes transceives signals from and to a programmer provided with a radio frequency transceiver to eliminate hardwiring between the surface electrodes and the programmer. The system reduces the need for supply line frequency filtering and isolation circuitry to protect against high voltage defibrillation shocks.
