ABSTRACT:
Methods and devices (e.g., pacemakers or ICDs with pacemaker functions) are provided for maintaining a high percentage of bi-ventricular pacing after a pacemaker switches from an atrial tracking bi-ventricular pacing mode to a non-atrial tracking bi-ventricular pacing mode, wherein the ventricles are paced in accordance with a mode switch base rate (MSBR) during the non-atrial tracking ventricular pacing mode. Monitoring is performed to determine whether or not pacing in according with the MSBR satisfies a minimum acceptable pacing criterion (MAPC). The MSBR is increased and pacing is performed in accordance with the increased MSBR, when the MAPC is not satisfied. The MSBR is decreased (e.g., periodically) and pacing is performed in accordance with the decreased MSBR when the MAPC is satisfied.
