1. A medical device, comprising:
a sensing circuit configured to:
receive a first cardiac electrical signal; and
sense first cardiac events each associated with a myocardial depolarization from the first cardiac electrical signal;
a control circuit coupled to the sensing circuit and configured to:
detect tachycardia from the first cardiac electrical signal;
set an ATP interval; and
set a first extended ATP interval that is longer than the ATP interval; and
a therapy delivery circuit coupled to the control circuit and configured to deliver a first therapy following the detection of the tachycardia by the control circuit by:
delivering a first leading ATP pulse at the first extended ATP interval from a first one of the first cardiac events sensed by the sensing circuit from the first cardiac electrical signal; and
delivering a second ATP pulse at the ATP interval from the first leading ATP pulse.
