Radiofrequency ablation of cardiac arrhythmia: the first fifty cases experience in Siriraj Hospital.

In our series of 50 consecutive patients with a wide variety of cardiac arrhythmia, a combined approach to electrophysiological diagnosis and definitive treatment with catheter ablation was associated with a high degree of efficacy, low procedural complication and low rate of arrhythmia recurrence. The radiofrequency catheter ablation should be considered as the acceptable or preferable first line treatment in patients with supraventricular tachycardia and idiopathic ventricular tachycardia.
