    摘要： An implantable cardiac stimulation device and method provide electrical stimulation therapy to stabilize the ventricular rate of a heart during episodes of atrial fibrillation. The stimulation therapy may be a plurality of stimulation pulses delivered to the AV node during the AV node refractory period following the sensing of an atrial event. Alternatively, the stimulation therapy may be a plurality of sub-threshold stimulation pulses delivered to capture AV node vagal innervations following the detection of atrial fibrillation.

    摘要： Techniques are provided for evaluating and optimizing the contribution of particular heart chambers to pacing efficacy. Briefly, a pacemaker temporarily alters the mode with which pacing therapy is delivered so as to selectively alter the heart chambers that are paced. The pacemaker detects any transient changes in pacing efficacy following the alteration in pacing mode. The pacemaker then assesses the contribution of particular heart chambers to pacing efficacy based on the alteration in the pacing mode and on any transient changes in the pacing efficacy. Additionally, techniques are provided herein for automatically adjusting pacing parameters to optimize the contribution of particular chambers to pacing efficacy.

    摘要： Implantable systems, and methods for use therein, perform at least one of a cardiac assessment and an autonomic assessment. Short-term fluctuations in PR intervals, that follow the premature contractions in the ventricles, are monitored. At least one of a cardiac assessment and an autonomic assessment is performed based on the monitored fluctuations in PR intervals that follow the premature contractions in the ventricles. This can include assessing a patient's risk of sudden cardiac death (SCD), assessing a patient's autonomic tone and/or detecting myocardial ischemic events based on the monitored fluctuations in PR intervals that follow the premature contractions in the ventricles.

    摘要： Techniques are provided for detecting and distinguishing stroke and cardiac ischemia based on electrocardiac signals. In one example, the device senses atrial and ventricular signals within the patient along a set of unipolar sensing vectors and identifies certain morphological features within the signals such as PR intervals, ST intervals, QT intervals, T-waves, etc. The device detects changes, if any, within the morphological features such as significant shifts in ST interval elevation or an inversion in T-wave shape, which are indicative of stroke or cardiac ischemia. By selectively comparing changes detected along different unipolar sensing vectors, the device distinguishes or discriminates stroke from cardiac ischemia within the patient. The discrimination may be corroborated using various physiological and hemodynamic parameters. In some examples, the device further identifies the location of the ischemia within the heart. In still other examples, the device detects cardiac ischemia occurring during stroke.

    摘要： An implantable cardiac defibrillation device provides pre-shock stimuli to reduce the defibrillation threshold (DFT). The device includes an arrhythmia detector that detects fibrillation of a fibrillating chamber of a heart and a pulse generator that provides a fibrillation therapy output responsive to the arrhythmia detector detecting fibrillation of the fibrillating chamber of the heart. The therapy output includes a defibrillating shock having an output magnitude exceeding a temporary defibrillation threshold of the fibrillating chamber and at least one pre-defibrillating shock output pulse that reduces an initial defibrillation threshold of the fibrillating chamber to the temporary defibrillation threshold. An electrode system having at least two defibrillation electrodes delivers both the at least one pre-defibrillating shock output pulse to the heart and the defibrillating shock to the fibrillating chamber of the heart.
