Six of these views are vertical (using frontal leads I, II, and III and limb leads aVR, aVL, and aVF), and 6 are horizontal (using precordial leads V1, V2, V3, V4, V5, and V6). The 12-lead ECG is crucial for establishing many cardiac diagnoses (see table Interpretation of Abnormal ECGs), including: Arrhythmias, Myocardial ischemia, Atrial enlargement, Ventricular hypertrophy and Conditions that predispose to syncope or sudden death (eg, Wolff-Parkinson-White syndrome, long QT syndrome, Brugada syndrome).
