Abstract

Leadless pacemakers (LPs) and systems for use therewith are disclosed. During a first period of time, during which an LP (102a, 102b) receives event messages from a second LP (102b, 102a), the LP (102a, 102b) times its pacing of a first cardiac chamber based on the event messages received from the second LP (102b, 102a) so that AV synchrony is maintained, and the LP (102a, 102b) determines and stores count value(s). Based on at least one of the count value(s), the LP (102a, 102b) determines a compensation offset indicative of a drift between timing circuitry (160) of the LP (102a, 102b) and timing circuitry (160) of the second LP (102b, 102a). During a second period of time, during which the LP (102a, 102b) does not receive event messages from the second LP (102b, 102a), the LP (102a, 102b) times its pacing of the first cardiac chamber based on the compensation offset to thereby compensate for the drift so that the AV synchrony is also maintained during the second period of time.
