We report a case with SVC ectopy initiating AF; the origin and breakout point of the sinus node was inside the SVC, and the SVC ectopy was conducted through the same path as the sinus node activation to depolarize the right atrium. Injury to the sinus node happened after successful isolation of SVC.
我们报告一例由上腔静脉(SVC)异位搏动引发房颤的病例;窦房结的起源和突破点位于SVC内,且SVC异位搏动通过与窦房结激动相同的路径传导,使右心房去极化。在成功隔离SVC后发生了窦房结损伤。
