Abstract:
1. A method for quantification of a desynchronization between two clocks of a system comprising at least two active implantable medical devices that communicate wirelessly, including: a first active implantable medical device comprising a first slow clock having a slow clock pulse rate, a first transmitter/receiver, and a first digital processing circuit clocked by the first slow clock; and a second active implantable medical device comprising a second slow clock having said slow clock pulse rate, a second transmitter/receiver, and a second digital processing circuit clocked by the second slow clock, wherein the first active implantable medical device and the second active implantable medical device are configured to communicate wirelessly by human body communication signals (HBC signals), wherein the HBC signals comprise pulse trains conducted by interstitial tissues of the body, and wherein the first transmitter/receiver and the second transmitter/receiver are configured to transmit and receive the HBC signals; wherein the first active implantable medical device includes a first fast clock having a fast clock pulse rate, the fast clock pulse rate being faster than the slow clock pulse rate; the quantification method comprising the steps of:
