This study is aimed to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach using Ensite NavX with conventional fluoroscopic approach using Ensite NavX plus fluoroscopy for the ablation of paroxysmal supraventricular tachycardia.

Fluoroscopy is the imagine modality routinely used in catheter ablation of cardiac arrhythmias. As we all know,fluoroscopic radiation is harmful both to the patients and the operation staffs. Recently,three-dimensional navigation systems have been developed and implemented in electrophysiological procedures for guiding catheters inside the heart chambers. Among the three-dimensional navigation systems, Ensite NavX is a promising system used for zero-fluoroscopic approach for performing catheter ablation of paroxysmal supraventricular tachycardia. This study is aimed to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach using Ensite NavX with conventional fluoroscopic approach using Ensite NavX plus fluoroscopy for the ablation of paroxysmal supraventricular tachycardia.

Paroxysmal supraventricular tachycardia will be ablated under the guidance of Ensite NavX and without the use of fluoroscopy.
