1. A medical device comprising:
a motion sensor configured to sense a motion signal;
a therapy delivery circuit configured to generate ventricular pacing pulses; and
a control circuit configured to:
determine a first feature of a first ventricular systolic event signal of the motion signal following a first ventricular pacing pulse of the ventricular pacing pulses;
determine a synchrony metric based on at least the determined first feature of the first ventricular systolic event signal;
determine that the synchrony metric does not meet a threshold; and
in response to the synchrony metric not meeting the threshold, adjust a pacing interval for scheduling a second ventricular pacing pulse of the ventricular pacing pulses generated by the therapy delivery circuit.
