Table 2: Main electrocardiographic features of the epicardiac ventricular arrhythmias. |
Epicardiac ventricular arrhythmia features |
Pseudo-delta wave > 34 ms |
Intrinsecoid deflexion in V2 > 85 ms |
Shorter RS complex > 121 ms |
Maximum deflexion index in precordial leads > 0.55 (onset to QRS peak/total QRS duration) |
Q wave in DI (antero-lateral epicardiac ventricular arrhythmia) |
Q wave in inferior leads (inferior epicardiac ventricular arrhythmia) |
