    • A post-surgical atrial cardioverting, atrial pacing, and ventricular pacing system and lead system provides for cardioverting the atria, pacing the atria, and/or pacing the ventricles of the heart of a post-surgical heart patient. The system includes a first lead and a second lead providing a pair of atrial cardioverting electrodes, an atrial pacing electrode, and a ventricular pacing electrode. The electrodes are electrically isolated from each other. The system further includes at least one anchor releasably disposing the electrodes beneath the skin of the patient with each atrial cardioverting electrode electrically contacting a respective given one of the atria, the atrial pacing electrode electrically contacting one of the atria, and the ventricular pacing electrode electrically contacting a ventricle. The system further includes at least one of an external cardiovertor coupled to the cardioverting electrodes for cardioversion, an external atrial pacer coupled to the atrial pacing electrode and one of the atrial cardioverting electrodes for pacing the atria, and an external ventricular pacer coupled to the ventricular pacing electrode and one of the atrial cardioverting electrodes for pacing the ventricles.

    • An implantable atrial defibrillator provides a pulse of defibrillating electrical energy to the atria of the heart in synchronism with sensed R waves in response to non-coincident sensing of an R wave at first and second areas of the heart. The defibrillating pulse is provided after a predetermined number of consecutive R waves are non-coincidently sensed to assure reliable synchronization. The atrial defibrillator is also operational in a marker mode wherein a number of synchronization marker pulses are delivered to the heart for detection on an externally generated electrocardiogram. The atrial fibrillation detector of the defibrillator is normally disabled and is activated when the sensed ventricular activity indicates a probability of atrial fibrillation to conserve a depletable power source. An endocardial lead is also described which ensures that the delivered atrial defibrillating electrical energy is substantially confined to the atria of the heart.
    • 可植入心房除颤器响应于在心脏的第一和第二区域处的R波的不一致的感测,与感测到的R波同步地向心脏的心房提供除颤电脉冲。 在不一致地感测到预定数量的连续R波之后提供除颤脉冲,以确保可靠的同步。 心房除颤器还可以在标记模式中操作,其中多个同步标记脉冲被传送到心脏以便在外部产生的心电图上进行检测。 除颤器的心房颤动检测器通常被禁用,并且当感测到的心室活动指示心房颤动的概率以节省可消耗的电源时被激活。 还描述了一种心内膜导联,其确保输送的心房除颤电能基本上限于心脏的心房。
