The 12 Lead ECG During Ventricular Tachycardia: Still an Important Tool for Ventricular Tachycardia Localization in Structural Heart Disease

The use of the 12-lead ECG recorded during ventricular tachycardia (VT) to regionalize its origin was first described by Josephson and colleagues in 1981 (1). The paper had 11 figures, unheard of by current publication standards, each showing one to five 12-lead ECG patterns during VT corresponding to a region of origin on the cardiac silhouette. Specific, but relatively simple rules based on the 12-lead ECG pattern were described. Basal left ventricular (LV) VTs have large R-waves across most precordial leads while apical VTs have no or poor R-wave progression or early regression.
