1. An implantable medical device comprising a telemetry module with a transmitter and a receiver and an input module being connectable to at least one electrode, the input module being adapted to obtain electrophysiological and/or hemodynamical signals from the heart via the at least one electrode at a predetermined sampling frequency, the device further comprising;

  • a storage unit for storage of the obtained electrophysiological and/or hemodynamical signals;

    a protocol module adapted to, at receipt of a protocol switch indication, activate and use a low power protocol for communication between said device and external units, wherein said protocol module is adapted to;

    select parts of stored electrophysical and/or hemodynamical signal waveforms for telemetric transmission;

    create communication packages having a predetermined length using said selected parts of said electrophysiological and/or hemodynamical signal waveform;

    instruct said transmitter to transmit said communication packages at predetermined transmission intervals; and

    instruct said telemetry module to power down said transmitter during intermediate periods between said transmission intervals.
