Follow-up of children or teenagers with paroxysmal supraventricular tachycardia, but without pre-excitation syndrome.
Paroxysmal supraventricular tachycardia (SVT) is considered benign in children if the electrocardiogram in sinus rhythm is normal, but causes anxiety in parents, children and doctors. ⋯ At the time of ablation, SVT management remains difficult in children. Indications for ablation are more common in AVRT than in AVNRT, but failures are frequent; 22.0% remained symptomatic after successful ablation, but false recurrences were frequent (15.4%). Without ablation, one third had a spontaneous favourable evolution.
