Atrial diagnostics in a tiered therapy implantable defibrillator

Abstract

Dual chamber sensing has been proposed in implantable defibrillators as an additional diagnostic modality for enhanced differentiation of ventricular and supraventricular tachycardias. A patient with different rates of wide QRS complex tachycardias is described in whom a tiered therapy implantable defibrillator with atrial sensing capability was implanted. Atrial diagnostic data in this patient enabled definitive diagnosis of his ventricular tachycardias and guided management decisions of his arrhythmia.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
