Electrophysiology (EP) study was planned with two or three catheters. Area of ablation determined by voltage mapping, propagation sinus wave collision and slow pathway potential location.

The median weight at ablation was 11.4\u00a0kg (range 8.9\u201314.9\u00a0kg). Median follow\u2010up time was 16 months. All had typical AVNRT.
