摘要

持续的室上性心动过速导致心律失常性心肌病（AIC）并不罕见。我们报告一个这样的情况下，一个持续多药耐药局灶性左房性心动过速（AT）在一个儿童谁提出了AIC。在电生理学研究中，这种心动过速定位于左心耳（LAA），但在该部位进行心内膜消融仅能暂时抑制心律失常。心外膜邻近心内膜区域的消融术可有效终止心动过速，并在最初48小时内改善左心室功能。因此，本病例报告强调由LAA引起的罕见心外膜AT的心外膜消融。

Successful epicardial ablation of incessant left atrial tachycardia in a child with arrhythmia induced cardiomyopathy.

Incessant supraventricular tachycardias leading to arrhythmia induced cardiomyopathy (AIC) is not uncommon. We report one such case of an incessant multidrug resistant focal left atrial tachycardia (AT) in a child who presented with AIC. During electrophysiology study this tachycardia was localized to the left atrial appendage (LAA) but, endocardial ablation at this site caused only temporary suppression of arrhythmia. The epicardial ablation at the site adjacent to the endocardial area proficiently terminated the tachycardia and improved the left ventricular function within the first 48 hours itself. Thus, this case report emphasizes the epicardial ablation of rare epicardial AT arising from LAA.
