Overview

The underlying cause of wide complex tachycardia tends to be ventricular tachycardia (VT) in patients > 35 years of age (sensitivity of 92% and a positive predictive value of 85% for VT) and supraventricular tachycardia (SVT) with aberrancy in patients < 35 years of age (positive predictive value of approximately 70%).
