糖尿病继发性体位性心动过速综合征2例报告并文献复习

Diabetic Secondary Postural Orthostatic Tachycardia Syndrome:Two Cases Report and Literature Review

目的:探讨体位性心动过速综合征(Postural Orthostatic Tachycardia Syndrome,POTS)的分类、发病机制、临床特点、诊断及治疗,提高对其认识。方法:采用回顾性研究方法,报告2例成人POTS临床资料、电生理及直立倾斜试验(Head-upright tilt test,HUTT)情况。结果:2例均有糖尿病史,血糖控制不理想,有脑干梗塞,交感皮肤反应(SSR)提示周围自主神经病变,HUTT提示POTS。结论:HUTT可用于POTS诊断,结合电生理自主神经功能检查有利于发现糖尿病继发性POTS。

Objective：To analyze the classification,pathogensis, clinical characteristics, diagnosis and management of diabetic postural orthostatic tachycardia syndrome （POTS） and to improve our understanding of this syndrome. Methods ：The data of the clinical manifestation and examinations of two adult patients with diabetic POTS were studied retrospectively. Results：Both patients suffered from diabetes and cerebral infarction in the brain stem. Sympathetic skin reaction （SSR） were abnormal. Head-upright tilt test （HUTT） showed POTS. Conclusion ：The diagnosis of POTS can be made by HUTT. Combined with electrophysiological examination such as SSR, HUTT can help to diagnose secondary POTS associated with diabetes.
