Abstract

An implantable medical device (1) configured to provide for an intra-cardiac pacing comprises an electrode arrangement (11, 12) configured to sense a cardiac sense signal and a processing circuitry (15) operatively connected to the electrode arrangement (11, 12). The processing circuitry (15) is configured to start a first timer (20) based on a ventricular sense event (Vs); to open an atrial detection window (T_sense) based on a first timer count output by the first timer (20); to start a second timer (24) in case an atrial sense event (As) is identified using the cardiac sense signal after opening the atrial detection window (T_sense); to identify a first timeout (TO1) based on a comparison of a second timer count output by the second timer (24) and a first pacing delay (AVD) indicative of a delay after which a ventricular pace signal should be triggered following a prior atrial sense event (As); to identify a second timeout (TO2) based on a comparison of the first timer count output by the first timer (20) and a second pacing delay (VVD) indicative of a delay after which a ventricular pace signal should be triggered following a prior ventricular sense event (Vs) or ventricular pace event (Vp); to identify a third timeout (TO3) based on a comparison of the first timer count output by the first timer (20) and a basic rate interval (BRI) indicative of a longest allowable interval without a ventricular sense event (Vs) or ventricular pace event (Vp); and to trigger a ventricular pace signal based on an identification of at least one of the first timeout (TO1), the second timeout (TO2) and the third timeout (TO3).
