Recovery pattern of left ventricular dysfunction following radiofrequency ablation of incessant supraventricular tachycardia in infants and children

摘要

Conclusions-Tachycardia induced car- diomyopathy is reversible following cura- tive treatment with readiofrequency. Recovery of left ventricular systolic func- tion precedes recovery of left ventricular dilatation. Time course to recovery is shorter in younger children. Objective-To assess recovery pattern of left ventricular function secondary to incessant tachycardia after radiofre- quency ablation I a group of infants and children. Design and setting-A combined prospec- tive and retrospective echocardiogrzphic study carried out in a tertiary paediatric cardiac centre.
