Permanent junctional re-entry tachycardia. A multicentre long-term follow-up study in infants, children and young adults

Abstract

Permanent junctional re-entry tachycardia in our experience is an arrhythmia with a large variety of clinical symptoms. Patients with a slow tachycardia rate and infrequent episodes of tachycardia may never develop symptoms and therefore do not need any therapy. Patients with frequent permanent junctional re-entry tachycardia, a fast tachycardia rate and impaired left ventricular function need effective therapy. In infancy and early childhood medical therapy is recommended as a first option, whereas in older and symptomatic patients catheter ablation is an effective and safe procedure.
