    • Cardiac monitoring and/or stimulation methods and systems provide for monitoring, diagnosing, defibrillation and pacing therapies, or a combination of these capabilities, including cardiac systems incorporating or cooperating with neuro-stimulating devices, drug pumps, or other therapies. Embodiments of the present invention relate generally to implantable medical devices employing automated cardiac activation sequence monitoring and/or tracking for arrhythmia discrimination. Embodiments of the invention are directed to devices and methods involving sensing a plurality of composite cardiac signals using a plurality of implantable electrodes. A source separation is performed using the sensed plurality of composite cardiac signals and the separation produces one or more cardiac signal vectors associated with one or more cardiac activation sequences that is indicative of ischemia. A change of the one or more cardiac signal vectors is detected using the one or more cardiac signal vectors. Cardiac arrhythmias are discriminated using the one or more cardiac signal vectors.
    • 心脏监测和/或刺激方法和系统提供监测,诊断,除颤和起搏治疗,或这些功能的组合,包括结合或与神经刺激装置,药物泵或其他疗法组合的心脏系统。 本发明的实施方案一般涉及使用自动心脏激活序列监测和/或跟踪用于心律失常鉴别的可植入医疗装置。 本发明的实施例涉及使用多个可植入电极感测多个复合心脏信号的装置和方法。 使用感测的多个复合心脏信号进行源分离,并且分离产生与指示缺血的一个或多个心脏激活序列相关联的一个或多个心脏信号载体。 使用一个或多个心脏信号矢量检测一个或多个心脏信号矢量的改变。 使用一个或多个心脏信号载体来区分心律失常。

    • A method or system for computing and/or setting optimal cardiac resynchronization pacing parameters as derived from intrinsic conduction data is presented. The intrinsic conduction data includes intrinsic atrio-ventricular and interventricular delay intervals which may be collected via the sensing channels of an implantable cardiac device. Among the parameters which may be optimized in this manner are an atrio-ventricular delay interval and a biventricular offset interval. In one of its aspects, the invention provides for computing optimum pacing parameters for patients having some degree of AV block or with atrial conduction deficits. Another aspect of the invention relates to a pacing mode and configuration for providing cardiac resynchronization therapy to patients with a right ventricular conduction disorder.
    • 提出了一种用于计算和/或设置从内在传导数据导出的最佳心脏再同步起搏参数的方法或系统。 内在传导数据包括可通过可植入心脏装置的感测通道收集的本征心室和室间延迟间隔。 可以以这种方式优化的参数是心房延迟间隔和双心室偏移间隔。 在其一个方面,本发明提供了对具有一定程度的AV阻滞或具有心房传导缺陷的患者计算最佳起搏参数。 本发明的另一方面涉及用于向患有右心室传导障碍的患者提供心脏再同步治疗的起搏模式和配置。
