This study investigated the association between concurrent typical atrial flutter and cavotricuspid isthmus (CTI) ablation and the recurrence of atrial arrhythmia. The data were obtained from a multicenter registry of cryoballoon ablation for AF ( n  = 2,689). All the patients with typical atrial flutter underwent CTI ablation.

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.
