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) |
