    摘要: A lead for use with an implantable cardioverter/defibrillator system is disclosed. In the preferred embodiment, the lead combines a right ventricular endocardial electrode, a superior vena cava electrode and one or more atrial sensing electrodes on a single catheter lead. The distal end of the lead is transvenously implanted, typically through an incision in the cephalic or subclavian vein. The proximal end of the lead is then tunneled below the fascia to the location of the pulse generator. Ventricular sensing and/or pacing electrode(s) may also be included at the distal end of the combined lead to provide ventricular intracardiac electrogram sensing and bradycardia pacing.

    摘要: A heart pacemaker detects pace-terminable tachycardia conditions in the atrium of the heart in accordance with selected high rate, rate stability, sudden onset and sustained high rate criteria. When a pace-terminable tachycardia is detected, programmed treatment modalities are applied to attempt to terminate the tachycardia. The tachycardia is treated by applying timed bursts of electrical pulses in formats defined by programmed primary and secondary treatment modalities. The primary and secondary treatments may be applied in an order which is dependent upon the prior successful treatment of similar tachycardias. The pacemaker may also utilize remembered treatment values which were successfully applied to treat similar tachycardias. The pacemaker may be programmed to restart the primary and secondary modes of treatment in the event that the modes initially failed to terminate a tachycardia. The pacemaker may also be programmed to limit the rate of burst pulses to avoid overstimulating the heart.

    摘要: An electrode configuration for an automatic implantable cardioverter/defibrillator system and method for its use are disclosed. The electrode configuration includes a first catheter transvenously positioned with a first electrode near the distal end of the catheter positioned in the right ventricle of a patient's heart. A second catheter carries second and third electrodes with the second electrode positioned in the superior vena cava region and the third electrode positioned in the left innominate vein. The second and third electrodes of the second catheter are connected together. A fourth electrode at the tip of the first catheter functions as a sensing/pacing electrode. A fifth electrode in the form of a subcutaneous patch is also electrically coupled to the second and third electrodes. The electrode arrangement can be positioned without the need for a thoracotomy. With the method of the invention, the automatic implantable cardioverter/defibrillator senses life-threatening arrhythmic conditions of the heart and issues at least one cardioverting or defibrillating pulse that is applied between the right ventricular electrode and the connected superior vena cava, innominate vein and subcutaneous patch electrodes. The invention provides preferential steering of discharge current through the septum between the right and left ventricles of the heart. The first catheter may also include a pacing tip.
