【摘要】 目的 探讨不明原因晕厥患者在倾斜试验(TTT)过程中出现心律失常的原因以及这些心律失常与血管迷走性晕厥有无相关性。方法 对我院检诊的2 100例不明原因晕厥患者在TTT过程中出现的心律失常进行了统计、分析。 结果 出现心律失常1 150例。其中复合的窦性停搏、房性心律失常、房室传导阻滞均发生在晕厥或晕厥先兆症状出现时；而室性早搏出现于晕厥或晕厥先兆前；交界区性心律失常出现在晕厥或晕厥先兆当时或以后，平卧位后均逐渐消失。结论 除复合的窦性停搏及一过性II-III度AVB外的绝大多数心律失常是TTT过程中血管迷走性晕厥发作时的一种伴随现象，并非是引起患者晕厥或晕厥先兆的直接原因，且在晕厥患者的临床治疗中要加以区别对待。

【Abstract】
Objective To investigate the mechanism of arrhythmia appears in the tilt table testing in patients with unexplained syncope，and the relation between the arrhythmia and vasovagal syncope.MethodsArrhythmia appeared in the tilt table testing in 2 100 patients with unexplained syncope were analyzed. ResultsArrhythmia appeared in 1 150 patients. All sinus arrest, atrial arrhythmia and atroventricular block occurred in the course of syncope or the portent of syncope. Ventricular premature beats occurred before syncope or the portent of syncope. Atroventricular arrhythmia occurred after or in the course of syncope or the portent of syncope ......
