Abstract

This study evaluated the paced QT interval in the days after radiofrequency ablation of the atrioventricular junction in patients with chronic rapid atrial fibrillation. There is an abnormality in the dynamics of the paced QT interval until the second day after ablation, resulting in an increased duration when the paced heart rate is <75 beats/min.
