用食道电生理法测定久居高原窦缓者的窦房结功能。检出9例SNRT>1400ms者,经药物阻滞植物神经后,复测各项参数均正常,IHR。均高于IHRP的正常预计范围。且阻滞前后的SNRT、SNRTC有明显的差异。9例均无器质性心脏病或慢性高山病,并除外了致迷走神经高亢的其他因素。一例从海拔3680m移居2260m已六年,随访中见其症状逐渐减轻,心率有所提高,揭示此类窦房结功能障碍与高原居民的迷走神经张力增高有关。属于“迷走神经高敏型”病态窦房结综合症,是以心动过缓为表现的病窦中的一种类型。
Determination of sinoatrial node function in esophageal sinus by using esophageal electrophysiology. Nine patients with SNRT> 1400 ms were detected. After the drug blocked the autonomic nerve, the parameters of all the tests were normal and IHR. Higher than the normal expected range of IHRP. SNRT and SNRTC before and after the block are obviously different. None of the 9 patients had organic heart disease or chronic mountain sickness, with the exception of other factors that contributed to the hyperactivity of the goblet. A case from the elevation of 3680m 2260m has been six years, follow-up to see the symptoms gradually reduced, heart rate has increased, revealing such sinoatrial node dysfunction and plateau residents with increased vagal tone. Belongs to “vagal hypersensitivity” sick sinus syndrome, is characterized by bradycardia sick sinus in a type.
