Abstract

Telemetry transmitting apparatus and a method are provided for reception and transmission of heart related electrical signals, such as electrocardiogram (EKG) and/or cardiac pacemaker signals, from a plurality of electrodes coupled to the body of a medical patient. A receiving facility of the apparatus receives a plurality of analog signals representing at least the EKG signals. An output signal representing the EKG signals is formed and transmitted, via a wireless coupling, to a telemetry receiver. An analog output port is provided on the telemetry transmitting apparatus. The analog output port is also coupled to the receiving facility. A plurality of output signals representing the EKG signals is provided to the analog output port of the telemetry transmitting apparatus. The analog output port may be coupled to buffers at the input terminals of the apparatus. Alternatively, the output port may receive processed signals from the amplifier in the telemetry transmitter that are gain adjusted to emulate the unprocessed voltage signals of the EKG electrodes and then combined with a digital pace pulse signal so that the output signals include pacemaker pulse information.
