Narrow complex (supraventricular) tachycardias

Abstract

Patients experiencing a narrow complex tachycardia are usually at a lower risk than those in whom a broad complex tachycardia occurs. Therefore, in the UK cardiologists are frequently involved in broad complex dysrhythmias at an early stage, while general physicians and general practitioners will often have greater involvement in the management of patients with narrow complex arrhythmias. We describe the management of narrow complex arrhythmias likely to be encountered, including the ubiquitous atrial fibrillation.
