Using floating atrial electrodes to combat the rising tide of inappropriate defibrillator therapies.

Abstract

Despite various implantable defibrillator algorithms and strategies used to improve discrimination between potentially life-threatening ventricular arrhythmias (ventricular tachycardia/ventricular fibrillation [VT/VF]) and more benign supraventricular tachycardias (SVTs), this remains a problem. In addition to significant discomfort and impairment of quality of life, there is some suggestion that shocks may increase mortality.1 Recording atrial intracardiac electrograms during arrhythmic episodes would be expected to improve our ability to discriminate tachycardias and thus reduce the number of inappropriate shocks. It may also lead to the diagnosis of otherwise unsuspected atrial arrhyhmias that may require specific therapy, such as anticoagulation therapy for patients with atrial flutter or atrial fibrillation (AF).
