Claim:
1. An implantable pacing device comprising: a housing configured to be implanted within a chamber of a heart of a patient; an electrode pair, wherein at least a first electrode of the electrode pair is carried on the housing; a signal generator configured to deliver cardiac pacing therapy to the heart of the patient, wherein the cardiac pacing therapy includes at least one pacing pulse that is divided into two or more pacing windows separated by one or more periods of substantially no electrical stimulation, the one or more periods of substantially no electrical stimulation being between about 0.1 milliseconds to about 20 milliseconds; a shock detector configured to obtain an electrical signal sensed via the electrode pair during the periods of substantially no stimulation of the pacing pulse and detect an anti-tachyarrhythmia shock during the periods of substantially no stimulation of the pacing pulse when the sensed electrical signal has one or more signal characteristics of an anti-tachyarrhythmia shock; and a processor configured to alter the cardiac pacing therapy in response to detection of the anti-tachyarrhythmia shock.
