Validation of a Simple Electrocardiographic Algorithm for Detection of Ventricular Tachycardia.

Background: The differential diagnosis of wide QRS complex tachycardia (WCT) between ventricular tachycardia (VT) or supraventricular tachycardia with aberrant conduction (SVT-A) is sometimes difficult in the emergency room.

Objective: The aim of this study was to evaluate the accuracy of a new simple electrocardiographic algorithm to recognize VT in patients with wide complex tachycardia.

Methods: The 12-lead electrocardiograms (ECG) for WCT were prospectively obtained from 120 patients during electrophysiological study.
