1. A medical device comprising:
a motion sensor configured to sense a motion signal;
a control circuit configured to:
determine at least one ventricular event metric from the motion signal sensed over a plurality of atrial cycles;
determine that the at least one ventricular event metric meets atrioventricular block criteria; and
generate an output in response to determining that the ventricular event metric meets the atrioventricular block criteria; and
a memory configured to store the generated output,
wherein the control circuit is configured to determine the at least one ventricular event metric by determining an integration metric based on sample point amplitudes of the motion signal during at least a portion of each atrial cycle of the plurality of atrial cycles.
