1. A method of determining a desynchronization between a first implantable medical device and a second implantable medical device, the method comprising:

  • receiving a synchronization query from the first implantable medical device at the second implantable medical device, the synchronization query being transmitted in response to the first implantable medical device detecting a predetermined transition of a first clock of the first implantable medical device, the first clock having a first pulse rate;

    determining a number of pulses of a second clock of the second implantable medical device occurring between reception of the synchronization query and a predetermined transition of a third clock of the second implantable medical device, the third clock having the first pulse rate, and the second clock having a second pulse rate higher than the first pulse rate; and

    determining the desynchronization between the first implantable medical device and the second implantable medical device based on the determined number of pulses of the second clock.
