摘要

上腔静脉(SVC)是心房颤动(AF)重要的非肺静脉病灶，被认为是瘢痕性心房心动过速(AT)的致心律失常部位。疤痕相关的ATs可能发生在导管消融和心内直视手术后;然而，特发性AT很少发生。案例演示。一位终末期糖尿病肾病患者，77岁，男，主诉因房颤引起的透析性低血压，入院行导管消融治疗。在这里，我们报告一例非医源性的8个AT在SVC的定位再入图。结论:SVC具有再入性心动过速致心律失常的潜力，制图技术的发展可以揭示其致心律失常的机制。

Non-Iatrogenic Localized-Reentrant Figure of Eight Atrial Tachycardias in the Superior Vena Cava.

Introduction: The superior vena cava (SVC) is an important non-pulmonary venous foci of atrial fibrillation (AF) and is known as the arrhythmogenic site of scar-related atrial tachycardia (AT). Scar-related ATs may occur after catheter ablation and open heart surgery; however, idiopathic AT rarely occurs. Case Presentation. A 77-year-old male with terminal diabetic nephropathy complained of dialysis-induced hypotension due to AF and was admitted to our hospital for catheter ablation. Here, we report a case of non-iatrogenic localized-reentrant figure of eight AT in the SVC.

Conclusion: SVC has the arrhythmogenic potential for re-entrant tachycardia, and the development of mapping technology can reveal arrhythmogenic mechanisms.
