Abstract

Distinction between ventricular tachycardia (VT) and supraventricular tachycardia (SVT) with aberrant conduction has major therapeutic and prognostic implications. Exclusive assessment of lead aVR, using a fourstep algorithm can rapidly make such distinction with a high degree of diagnostic accuracy. To illustrate the concept, we present the case of a 70-year-old female with a prior history of supraventricular dysrrhythmias, who presented with a wide-complex tachycardia.
Keywords: supraventricular tachycardia; ventricular tachycardia; lead aVR supraventricular tachycardia; ventricular tachycardia; lead aVR
