Abstract

A leadless pacemaker device for providing an intra-cardiac pacing includes processing circuitry configured to generate ventricular pacing signals for stimulating ventricular activity at a ventricular pacing rate, a first sensor configuration receiving a first sense signal, and a second sensor configuration receiving a second sense signal. The processing circuitry derives, in a first sensing state, atrial events from the first sense signal for controlling the ventricular pacing rate based on the atrial events. The processing circuitry switches, based on at least one switching criterion, from the first sensing state to a second sensing state in which the processing circuitry derives atrial events from the second sense signal. The second sense signal is received by the second sensor configuration for detection of atrial events and the second sensor configuration is a motion sensor or a sound sensor. A method for operating the pacemaker device is also provided.
