      【摘要】 目的 动态观察血管迷走性晕厥(Vasovagal syncope，VVS)患者发作后的心率震荡(Heart rate
turbulence, HRT)变化。方法 对42例临床诊断为VVS患者在发作当日、1周后、3个月后以及40例年龄、性别匹
配的健康体检者进行动态心电图检查，并进行震荡初始和震荡斜率分析。结果 VVS患者发作当日以及TO、TS
异常比例与健康对照组比较差异均有统计学意义。1周、3个月后随访观察TO、TS异常率与健康对照组相比无
统计学意义。结论 VVS患者发作当日存在明显的HRT现象异常，HRT可能是诊断VVS的一种简便方法。

【Abstract】 Objective To observe the changes of heart rate turbulence (HRT) in patients suffering vasovagal
syncope. Methods The dynamic electrocardiograms of 42 newly-onset patients with vasovagal syncope (the study
group) were recorded on the day syncope happened, 1 week later and 3 months later. Forty age-matched healthy individ-
uals (the control group) also underwent dynamic electrocardiogram examination. The turbulence onset (TO) and turbu-
lence slope (TS) were analyzed. Results The average and abnormality rate of TO and TS showed statistically signifi-
cant difference between the two groups on the day syncope happened (P<0.05), which showed no statistically significant
difference 1 week later and 3 months later (P>0.05). Conclusion The patients suffering vasovagal syncope have abnor-
mal HRT on the day syncope happened, thus HRT maybe a simple diagnostic method of vasovagal syncope.
