Abstract
Recognizing that delivery of pacing therapy to a patient may increase the risk of inappropriate delivery of anti-tachyarrhythmia therapy, a modified atrial-based timing device and method delivers pacing and anti-tachyarrhythmia therapy to the patient such that the risk is reduced. A ventricular-atrial (VA) time interval is increased, when an intrinsic ventricular activation is sensed during an atrial-ventricular (AV) time interval, by the time remaining in the immediately preceding AV time interval following the intrinsic ventricular activation sensed therein. As a result, the patient's heart rate is not elevated, in response to ventricular activations sensed during the AV time interval, and a tachyarrhythmia rate threshold is not exceeded, thereby avoiding inappropriate delivery of anti-tachyarrhythmia therapy.
