T wave oversensing in implantable cardioverter defibrillators.
The implantable cardioverter defibrillator is the treatment of choice for patients with ventricular tachycardia, especially in the setting of structural heart disease, but inappropriate therapy continues to be a problem. In this report we describe a short case series of patients who presented with T wave oversensing. We propose a classification in 2 categories, T wave oversensing occuring in the setting of persistently low R wave amplitude, and T wave oversensing occuring in the setting of transiently low R wave amplitude.
