AV delay features

摘要

An atrial event and a ventricular event can be received, and an atrioventricular (AV) delay can be provided using information about the atrial and ventricular events. The AV delay can be increased after a first condition is satisfied to allow a heart to regain intrinsic control of ventricular activation, and changed after a second condition is satisfied to allow the heart to remain in intrinsic control of ventricular activation.

1. A system comprising:
a processor, comprising:
a first input configured to receive information about an atrial event; anda second input configured to receive information about a ventricular event;wherein the processor is configured to provide an atrioventricular (AV) delay using information about the atrial event and information about the ventricular event, and wherein the AV delay exceeds a constraint interval established using a maximum tracking rate (MTR) and a post ventricular atrial refractory period (PVARP).
