Claim 11:
12. A subcutaneous implantable cardioverter-defibrillator (SICD) comprising:
one or more leads configured to be implanted in a subcutaneous region of a subject, the one or more leads including multiple electrodes;
a case forming one of the multiple electrodes;
an accelerometer configured to sense accelerometer signals; and
a controller configured to:
apply anti-tachycardia pacing (ATP) therapy to the subject at a first time, via a first ATP combination of electrodes, the first ATP combination of electrodes comprising two or more of the multiple electrodes;
obtain first accelerometer signals responsive to applying the ATP therapy via the first ATP combination of electrodes;
apply ATP therapy to the subject at a second time, via a second ATP combination of electrodes, the second ATP combination of electrodes comprising two or more of the multiple electrodes;
obtain second accelerometer signals responsive to applying the ATP therapy via the second ATP combination of electrodes;
determine sizes of the first and second accelerometer signals; and
select one of the first ATP combination of electrodes or the second ATP combination of electrodes to use for delivery of subsequent ATP therapy based on the sizes of the first and second accelerometer signals.
