The signal replication medical apparatus includes an input adapted to receive at least one medical signal transmitted via a first medical device coupled to the body of a patient, signal processing circuitry adapted to generate at least one replicated signal from the at least one medical signal, and an output. The at least one replicated signal is indicative of being transmitted via a second medical device different than the first medical device. The output is adapted to deliver the at least one replicated signal to an external device configured to receive signals from the second medical device.
