Claim Text:
1. A method comprising: sensing an electrical cardiac signal using a leadless pacing device while the leadless pacing device is in an atrio-ventricular synchronous pacing mode; receiving, by a processing module, the electrical cardiac signal sensed by the leadless pacing device while the leadless pacing device is in the atrio-ventricular synchronous pacing mode; detecting, by a processing module, a first atrial activation event; determining, by a processing module and based on the electrical cardiac signal, a second atrial activation event was not detected within a detection window that begins at the first atrial activation event; and controlling, by the processing module, the leadless pacing device to deliver pacing pulses to a ventricle of a patient according to an asynchronous ventricular pacing mode based on the determination that the second atrial activation event was not detected within the detection window.
