Abstract

A system and method for long-term monitoring of cardiac conditions such as arrhythmias is disclosed. The invention includes a pulse generator including means for sensing an arrhythmia. The pulse generator is coupled to at least one subcutaneous electrode or electrode array for providing electrical stimulation such as cardioversion / defibrillation shocks and / or pacing pulses. The electrical stimulation may be provided between multiple subcutaneous electrodes, or between one or more such electrodes and the housing of the pulse generator. In one embodiment, the pulse generator includes one or more electrodes that are isolated from the can. These electrodes may be used to sense cardiac signals.

Description

FIELD OF THE INVENTION

[0001] This invention relates to a method and apparatus for treating ventricular arrhythmias; and more particularly, relates to a method and apparatus for long-term monitoring of arrhythmias, and for the delivery of acute tachyarrhythmia and bradyarrhythmia therapy using a subcutaneous stimulation device. DESCRIPTION OF THE PRIOR ART

[0002] It has long been known to use implantable systems to protect patients that are at risk for life-threatening arrhythmias. For example, rapid heart rhythms commonly referred to as tachyarrhythmias are generally treated using implantable devices such as the Medtronic Model 7273 GEM II DR or the 7229 GEM II SR, both commercially available from the Medtronic Corporation. These systems detect the presence of tachyarrhythmia conditions by monitoring the electrical and mechanical heart activity (such as intra-myocardial pressure, blood pressure, impedance, stroke volume or heart movement) and / or the rate of the electrocardiogram.
