1. A method for communicating between a plurality of medical devices, the method comprising:

  • generating, with a first medical device, a first non-pacing communication pulse at a first time and a second non-pacing communication pulse at a second time;

    receiving, with a second medical device, the first non-pacing communication pulse at a third time and the second non-pacing communication pulse at a fourth time;

    determining, by the second medical device, one of three or more symbols based at least in part on the time difference between the third time and the fourth time, wherein;

    a “

    0”

    symbol is determined if the difference between the third time and the fourth time is in a range of 350 to 450 microseconds;

    a “

    1”

    symbol is determined if the difference between the third time and the fourth time is in a range of 550 to 700 microseconds; and

    a synchronization symbol is determined if the difference between the third time and the fourth time is in a range of 800 to 1100 microseconds.
