    摘要: This document discusses, among other things, systems, devices, and methods for measuring cardiac impedances and producing one or more resynchronization index parameters each indicative of a cardiac synchrony or asynchrony using the measured cardiac impedances. In one example, the one or more resynchronization index parameters are used to adjust one or more pacing parameters of a cardiac resynchronization therapy.

    摘要: Various implantable medical device embodiments stimulate an autonomic neural target from within a pulmonary artery, and comprise at least one electrode, a power supply, a neural stimulator connected to the power supply, and an anchor structure. The neural stimulator is configured to generate a neural stimulation signal for delivery to the neural stimulation target through the at least one electrode. The anchor structure is configured to chronically and securely implant the neural stimulator, the power supply and the at least one electrode within the pulmonary artery. The anchor structure, the neural stimulator, the power supply and the at least one electrode are configured to be implanted through a pulmonary valve into the pulmonary artery. In various embodiments, the neural stimulator is configured to be operational to implement a neural stimulation protocol when chronically implanted within the pulmonary artery without a wired connection through the pulmonary valve.

    摘要: An implantable medical device senses a plurality of electrograms from substantially different atrial locations, detects regional depolarizations from the electrograms, and analyzes timing relationships among the regional depolarizations. The timing relationships provide a basis for effective therapy control and/or prognosis of certain cardiac disorders. In one embodiment, an atrial activation sequence is mapped to show the order of occurrences of the regional depolarizations during an atrial depolarization for classifying a detected tachyarrhythmia by its origin. In another embodiment, conduction time between two atrial locations is measured for monitoring the development of an abnormal atrial conditions and/or the effect of a therapy.

    摘要: A delivery system and method for delivering a right ventricular lead into a right ventricle includes a delivery device having an inflatable balloon at a distal end. The device is inserted into the venous system, the balloon is inflated and the device is floated along a blood flow path within the venous system through the heart and into the pulmonary artery. The lead is delivered into the right ventricle using the device. In one embodiment, the device is a catheter that facilitates placement of a guide wire into the right ventricle for delivery of the lead. The catheter is then removed and the lead is inserted into the right ventricle over the guide wire.

    摘要: A method and system for delivering anti-tachycardia pacing (ATP) is disclosed. By comparing the time intervals between senses from both ventricles, the origin of a ventricular tachyarrhythmia may be mapped to one or the other of the ventricles. The arrhythmic ventricle may then be paced with either single-ventricle or biventricular ATP pacing.
