Abstract Introduction Catheter-based radiofrequency (RF) ablation is generally regarded as the standard approach for patients with ventricular tachycardia (VT) refractory to antiarrhythmic drug therapy and may be considered as a first-line approach when there is a preference to avoid these agents.

Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. On the ECG, ventricular tachycardia can be defined as three or more ventricular ectopic beats occurring in a sequence at a rate more than 100 per minute. Another rare form of ventricular tachycardia is bidirectional ventricular tachycardia.
