Objectives

Narrative objectives1

Cryobaloon ablation for patients with atrial fibrillation is widely practiced worldwide including Japan as a safe and effective treatment. It has been reported that the nadir temperature of the cryoballoon is a predictor of myocardial injury during pulmonary vein isolation. And blood flow reduction in the left atrium by high frequency right ventricular pacing has been reported to contribute significantly reduction of the balloon temperature.
Right ventricular pacing is a procedure performed from an electrode catheter inserted in the right ventricle and has also been performed in daily cardiac electrophysiological examination, and its safety has been established.
We randomize the patients who underwent cryoballoon ablation in our institution to two groups whether or not high frequency right ventricular pacing is performed during cryoballoon freezing and observe prospectively the effect of myocardial injury and atrial fibrillation recurrence in the acute and chronic period.
