Junctional ectopic tachycardia in six paediatric patients

摘要

The presenting features and treatment responses of six children with junctional ectopic tachycardia are evaluated. Two of the patients were siblings and both pre- sented in early childhood with cardiopul- monary failure. The elder sibling died, the surviving sibling was controlled on a com- bination of amiodarone, digoxin, and sotalol. The remaining four patients pre- sented in later childhood with tachycardia induced cardiomyopathy. Two of the pa- tients were diagnosed incidentally and have normalised their myocardial func- tion on sotalol therapy. The other two pre- sented in congestive cardiac failure. Radiofrequency His bundle ablation and Insertion of a permanent pacemaker to control the arrhythmia was undertaken in the elder of the two patients.
