目的:探讨直立倾斜试验(HU TT)在不同年龄和性别的不明原因晕厥(UPS)患者诊断中的意义。方法:诊断为血管迷走性晕厥(VVS)的U PS患者14 9例,年龄4～70岁,平均(2 6 .78±16 .34)岁;男5 7例,女92例。采用电动倾斜床取头高脚低位直立倾斜70°后,每5 min自动测量血压和心电变化,评价HUTT结果。用SPSS11.0软件微机数理统计。结果:HU TT阳性率38.2 6 % (5 7/14 9例) ,女性占82 .4 6 % (47/5 7例)。直立倾斜(2 2 .74±14 .0 7) min时出现晕厥发作,≤18岁与>18岁两个亚组间〔分别为(2 0 .0 7±14 .10 ) m in与(2 5 .31±13.10 ) min〕差异未见显著性(P>0 .0 5 ) ,反应类型中血管抑制型为6 6 .6 7% (38/5 7例) ,心脏抑制型为2 2 .81% (13/5 7例) ,混合型为10 .5 2 % (6 /5 7例) ,且与年龄无关(P>0 .0 5 )。血管抑制型在女性较常见(5 7.9% ,P<0 .0 0 5 )。阳性组较阴性组HU TT结束时终末心率、终末收缩压及终末舒张压均显著降低(P<0 .0 5或P<0 .0 1)。阳性组男性患者终末心率、终末收缩压及终末舒张压较女性降低明显(P均<0 .0 5 )。将≤18岁亚组与>18岁亚组进行比较,阳性组前者起始收缩压及起始舒张压均降低(P均<0 .0 1) ,终末收缩压与终末舒张压亦降低(P均>0 .0 5 ) ,起始与终末心率稍增加(P均>0 .0 5 ) ;
Objective: To explore the significance of headup tilt table test (HUTT) in the diagnosis of patients with unexplained syncope (UPS) in different age and genders. Methods: One hundred and fortynine vasovagal syncope(VVS) patients (male 57, female 92) aged from 4 to 70 years old 〔mean(26.78±16.34)years〕 were made HUTT in 70 degree with electric power tilt table. A multifunctional monitor was used for the measurement of changes of blood pressure and electrocardiogram automatically every 5 minutes. The results of HUTT were evaluated. SPSS11.0 software was used for the statistic analysis of these data. Results: The positive rate of HUTT was 38.26% (57/149 cases) in patients of UPS, and in the female patients it was 82.46% (47/57 cases). The syncope episodes occurred after standing for 245 minutes 〔mean (22.74±14.07 ) minutes〕, and there was no difference in ≤18 years and >18 years subgroups 〔(20.07±14.10)minutes vs.(25.31±13.10)minutes, P>0.05〕. The blood vessel inhibited type of reaction occurred in 66.67% (38/57 cases) , heart inhibited type in 22.81%(13/57 cases) and mixed type in 10.52% (6/57 cases). The occurrence was not related to ages(P>0.05). The blood vessel inhibited type was common in female (57.9%, P<0.005). When HUTT was ended, the end heart rate, end systolic pressure and end diastolic pressure were decreased obviously in the positive than in negative patients(P<0.05 or P<0.01). The end heart rate, end systolic pressure and end diastolic pressure in male were lower than those in female in positive group(all P<0.05). The beginning systolic pressure and beginning diastolic pressure were decreased (both P<0.05), the end systolic pressure and end diastolic pressure were more lightly decreased(both P>0.05) and the heart rate more increased a little bit in ≤18 years subgroup than in >18 years subgroup in positive group (both P>0.05). The beginning and end diastolic pressures as well as systolic pressure were slightly raised in both ≤18 years and >18 years subgroups in negative group (al
