Abstract:
An implantable device for delivering anti-tachyarrhythmia therapy to a heart, the device comprising:an atrial receiver for receiving an atrial heart activity signal from an atrium of the heart;a ventricular receiver for receiving a ventricular heart activity signal from a ventricle of the heart;an atrial therapy circuit for delivering anti-tachyarrhythmia therapy to the atrium; anda controller, coupled to each of the atrial therapy circuit and the atrial and ventricular receivers, for controlling the delivery of the anti-tachyarrhythmia therapy to the atrium in response to the atrial heart activity signal indicating a need for anti-tachyarrhythmia therapy, and wherein the controller includes a first timer for delaying, for a first time delay, the delivery of the anti-tachyarrhythmia therapy to the atrium by a first time delay in response to the ventricular heart activity signal that includes an indication of abnormal susceptibility to a ventricular tachyarrhythmia.
