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 portable patient monitoring apparatus 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 a first output signal representing the patient'"'"'s condition and applying said first output signal to a first output port for transmitting said first output signal via a wireless transmission to a remote monitoring device;

    a second output port included as part of the wireless transmitting circuitry; and

    output circuitry coupled to the receiving circuitry for providing a second output signal representing the patient'"'"'s condition to the second output port of the wireless transmitting circuitry simultaneously with the wireless transmission of said first output signal to the remote monitoring device.
