摘要
目的:探讨室上性心动过速患者并发血管迷走性晕厥的发病情况。方法:应用直立倾斜试验加用或不加用异丙肾上腺素静脉滴注对22例室上性心动过速并发晕厥患者、29例不明原因晕厥者及23例健康无晕厥史者进行诱发试验。结果:室上性心动过速组的直立倾斜试验阳性率为63.6%,与不明原因晕厥组的75.8%基本相似(P>0.05),与对照组的17.4%有明显差异(P<0.001)。结论:室上性心动过速并晕厥患者与不明原因晕厥者在加用与不加用异丙肾上腺素诱发的直立倾斜试验阳性发生率无明显差别,其晕厥类型均属于血管迷走性晕厥,与血管减压机制有关,与快速心动过速的心室率无关。
Objective:To study the morbidity of vasovagal syncope in patients with supraventricular tachycardia. Methods:Tilt table testing with or without isoproterenol infusion was performed on 22 patients of syncope associated with supraventricular tachycardia,29 patients of unexplained syncope and 23 normal subjects. Results:The positive rate of tilt table testing in patients with supraventricular tachycardia was 63 6% which was similar to that in patients with unexplained syncope (75 8%, p >0 05),and that of the normal subjects was only 17 4%( p <0 001 vs.the other two groups). Conclusion:There was no significant difference in the positive rate between the supraventricular tachycardia group and unexplained syncope group.Patients with syncope in the two groups are caused by vasodepressor machanism and classified as vasovagal syncope which is not related to the heart rate in tachycardia.
