Key result
Idiopathic ventricular arrhythmias in children are usually benign, with spontaneous or post-treatment disappearance occurring in up to 65% of cases with ventricular tachycardia.
Idiopathic ventricular arrhythmias in children are usually benign and often resolve spontaneously, though catheter ablation is recommended if ventricular dysfunction or hemodynamic compromise occurs.
watchful waiting for stable pediatric idiopathic ventricular arrhythmias; leaves open the optimal timing for catheter ablation.
<ns3:p>Idiopathic ventricular arrhythmia in children is usually benign. Ventricular ectopy in children usually is an incidental finding. Prevalence varies with age: neonates nearly 20%, school age 10%, teenagers 20-30%. During natural history total or partial disappearance of idiopathic ventricular ectopy, spontaneously or after treatment was described in about 23% children with premature ventricular beats, 28% with pairs and 65% with ventricular tachycardia. Arrhythmia more often resolves in infants than in older children, more often in arrhythmia with right than left bundle branch block morphology. Idiopathic ventricular tachycardia or frequent ventricular ectopic beats may in small percentage of pediatric patients lead to ventricular dysfunction, but risk factors of this arrhythmic cardiomyopathy in children are not established. Catheter ablation is recommended in children with ventricular dysfunction or hemodynamic compromise presumed to be due to ventricular arrhythmia, as primary therapy or in patients with arrhythmia not controlled medically</ns3:p>
