摘要： A leadless pacemaker device (1) configured to provide for an intra-cardiac pacing comprises a processing circuitry (15) configured to generate ventricular pacing signals for stimulating ventricular activity at a ventricular pacing rate, a first sensor arrangement configured to receive a first sense signal, and a second sensor arrangement configured to receive a second sense signal. The processing circuitry (15) is configured to derive, in a first sensing state, atrial events (As) from the first sense signal for controlling the ventricular pacing rate based on said atrial events (As). The processing circuitry (15) is further configured to switch, based on at least one switching criterion, from the first sensing state to a second sensing state in which the processing circuitry (15) is configured to derive atrial events (As) from the second sense signal.
