Apparatus and method for providing dual output signals in a telemetry transmitter
First Claim
1. A portable patient monitoring apparatus adapted for being carried by a medical patient and having as its primary function the reception and then wireless transmission to a remote monitoring device of medical data acquired from the patient, and having a secondary function of also providing the medical data to an output port of the telemetry transmitter for facilitating local monitoring of the medical data, comprising:
- receiving circuitry adapted for being coupled to said patient for receiving a plurality of analog signals representing a sensed condition of the patient;
wireless transmitting circuitry, including a signal processor and a wireless signal transmitter coupled to the receiving circuitry for forming an output signal representing the patient'"'"'s condition and transmitting said output signal via a wireless transmission to a remote monitoring device;
an analog output port included as part of the wireless transmitting circuitry; and
output means coupled to the receiving circuitry for providing a plurality of analog output signals representing the patient'"'"'s condition to the analog output port of the wireless transmitting circuitry simultaneously with the transmission of said output signal to the remote monitoring device.

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.
