    摘要: A lead for monitoring or stimulating cardiac activity is provided. The lead is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead body has one or more electrodes associated therewith. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and urged into intimate contact a vessel wall. A method for implanting the lead into the coronary vasculature is also provided, the method comprising the steps of inserting a stylet into the lead, inserting the lead into the coronary sinus, advancing the lead from the coronary sinus toward the toward the left atrium and into a coronary vein, removing the stylet, and sensing and pacing the heart. Alternatively, the method comprises placing a guide catheter into the coronary sinus, threading a guide wire into the coronary veins, pushing the lead over the guide wire and into the coronary sinus or the coronary vein, and sensing and pacing the heart via the lead in its implanted site in the coronary sinus or the coronary vein.

    摘要: A first electrode is positioned within an artery proximate an implanted intravascular stent. A second electrode is positioned at a separate location relative the position of the first electrode. Electrical energy is then delivered between the first and the second electrodes to produce an electrical field adjacent the implanted intravascular stent. When a intravascular stent is implanted in a coronary artery, the delivery of the electrical energy is coordinated to cardiac cycles detected in sensed cardiac signals, where the delivery of the electrical energy between the first electrode and the second electrode occurs during a predetermined portion of the cardiac cycle.

    摘要: A cardiac rhythm management system, such as an implantable cardioverter-defibrillator (ICD), provides atrial anti-tachyarrhythmia therapy, such as a bipolar or unipolar electrical cardioversion countershock, or provides both atrial and ventricular anti-tachyarrhythmia therapy. The atrial and ventricular anti-tachyarrhythmia therapies have independent cardioversion-defibrillation energy levels and other parameters. The system provides an endocardial lead that is convenient to implant for providing anti-tachyarrhythmia therapy. The endocardial lead includes a first supraventricular electrode disposed in the atrium and superior vena cava, and optionally includes a first ventricular electrode and ICD housing electrode.

    摘要: A cardiac rhythm management device capable of delivering multiple uni-chamber stimulation pulses to a patient's heart and suitable for verifying capture independently for each uni-chamber stimulation pulse. The uni-chamber capture verification mode of the cardiac rhythm management device may be activated via telemetry or by applying a magnetic field proximate the device. During the capture verification mode, bi-chamber pacing, for example, may precede or follow uni-chamber pacing to allow for pacing support. Also, the energy levels of the pacing stimulus over several beats may be varied, thereby verifying the programmed safety margins.
