Cardiac dyssynchrony in patients with repaired Tetralogy of Fallot (rToF) has been attributed to right bundle branch block (RBBB), fibrosis and/or the patches that are inserted during repair surgery. We aimed to investigate the basis of abnormal activation in rToF patients by mapping the electrical activation sequence during sinus rhythm (SR) and right ventricular (RV) pacing.

法洛四联症修复术后传导延迟原因探讨

修复法洛四联症 (rToF) 患者的心脏不同步被归因于右束支传导阻滞 (RBBB)、纤维化和/或修复手术期间插入的补片。我们旨在通过绘制窦性心律 (SR) 和右心室 (RV) 起搏期间的电激活序列来研究 rToF 患者异常激活的基础。
