Abstract: An implantable cardioverter defibrillator (ICD) configured to transmit a tissue conduction communication (TCC) signal includes a TCC transmitter module configured to generate the TCC signal and transmit the TCC signal via a plurality of electrodes. The TCC signal comprises a biphasic signal having an amplitude and a frequency, wherein at least one of the amplitude and the frequency are configured to avoid stimulation of tissue of the patient. The TCC transmitter module comprises protection circuitry coupled between a current source and the plurality of electrodes, wherein the protection circuitry is configured to protect the signal generator from an external anti-tachyarrhythmia shock delivered to the patient.
