Swallowing-induced atrial tachycardia (SIAT) is a relatively rare arrhythmia. A 56-year-old woman was admitted to treat atrial tachycardia that occurs by not only eating and drinking but also yawning. Both the right and left upper pulmonary veins were suspected as the earliest activation site of the tachycardia and the abnormal activation of ectopies themselves were suppressed after pulmonary vein isolation (PVI). In a 24-hour Holter electrocardiogram, the HF component of the analysis of heart rate variability was suppressed both at 1 day and at 2 years after ablation. In this case, cardiac vagal nerve denervation by PVI was effective for SIAT.

肺静脉隔离去迷走神经对吞咽性房性心动过速有效

吞咽诱发的房性心动过速 (SIAT) 是一种相对罕见的心律失常。一名 56 岁的女性因治疗房性心动过速而入院，这种房性心动过速不仅会因进食和饮水而发生，还会因打哈欠而发生。左右上肺静脉均被怀疑为心动过速的最早激活部位，肺静脉隔离（PVI）后异位本身的异常激活被抑制。在 24 小时动态心电图中，心率变异性分析中的 HF 成分在消融后 1 天和 2 年均被抑制。在这种情况下，通过 PVI 去神经迷走神经对 SIAT 有效。
