    摘要: The bi-ventricular implantable pulse generator described and depicted herein enables hemodynamic efficiencies for patients suffering from intraventricular conduction delays or conduction blockage. The pulse generator effectively overcomes such conduction delay or block (e.g., left bundle branch block, “LBBB,” or right bundle branch block, “RBBB”) by delivering a novel form of cardiac resynchronization therapy (CRT). Specifically, a single ventricular pre-excitation pacing stimulus is triggered from an atrial event (e.g., intrinsic or evoked depolarization). The triggering event may emanate from the right atrium (RA) or the left atrium (LA). A single ventricular pre-excitation pacing stimulus is delivered prior to the intrinsic depolarization of the other ventricle and thus promotes intraventricular electromechanical synchrony during CRT delivery.

    摘要: An implantable device is described that collects and aggregates data from non-implanted medical devices external from a body of a patient. The device may also collect and aggregate data from medical devices implanted within the body. The implantable device includes a wireless transceiver to acquire physiological data from the external medical devices, and a storage medium to store the physiological data. A processor retrieves the physiological data and communicates the physiological data to a remote patient management system. The device may collect the physiologic data from the various external data sources, possibly over an extended period of time, and stores the data for subsequent upload to a common patient management system. In addition, the implantable device may collect physiological data from other medical devices implanted within the patient. In this manner, the device provides a central point for collection and aggregation of physiological data relating to the patient.

    摘要: Methods and devices for determining optimal Atrial to Ventricular (AV) pacing intervals and Ventricular to Ventricular (VV) delay intervals in order to optimize cardiac output. Impedance, preferably sub-threshold impedance, is measured across the heart at selected cardiac cycle times as a measure of chamber expansion or contraction. One embodiment measures impedance over a long AV interval to obtain the minimum impedance, indicative of maximum ventricular expansion, in order to set the AV interval. Another embodiment measures impedance change over a cycle and varies the AV pace interval in a binary search to converge on the AV interval causing maximum impedance change indicative of maximum ventricular output. Another method varies the right ventricle to left ventricle (VV) interval to converge on an impedance maximum indicative of minimum cardiac volume at end systole. Another embodiment varies the VV interval to maximize impedance change.
