Overview
Ventricular tachycardia refers to a rhythm with a heart rate in excess of 100 (and in some definitions 120) beats per minute that arises distal to the bundle of His. Ventricular tachycardia can be classified based on morphology and duration The morphology of the QRS complexes on the ECG maybe (monomorphic ventricular tachycardia vs polymorphic ventricular tachycardia). In sustained VT duration of VT lasts > 30 sec or VT< 30 sec that needs to termination due to compromised hemodynamic. Nonsustained, or unsustained VTis more than 3 consecutive premature ventricular complexes with spontaneously termination.
Classification Based Upon Morphology of the QRS Complexes
Classification of ventriculat arrhythmia:
| Term | Definition | Feature | |
|---|---|---|---|
| Ventricular tachycardia[1] | Presence of ≥ 3 consecutive premature ventricular complexes with the rate of >100 beats per minute or cycle length< 600 ms |  |
|
| Sustained VT |
|
||
| Nonsustained, or unsustained VT |
|
||
| Monomorphic VT |
|
||
| Polymorphic VT | |||
| Bidirectional VT |
|
||
| Torsades de pointes |
|
 |
|
| Ventricular flutter |
|
 |
|
| Ventricular fibrillation |
|
 |
|
| VT, VF storm |
