摘　　要：目的探讨直立倾斜试验（HUTT）结束后心率恢复到正常水平的时间。方法2004-01-2011-05在中南大学湘雅二医院进行HUTT患者919例，年龄2-74（18．4±14．0）岁，男439例，女480例，儿童及青少年组（〈18岁）646例，成人组（≥18岁）273例；HuTr阴性组439例，HUTT阳性组480例（其中血管抑制型380例，心脏抑制型5例，混合型95例）。分析HUTT结束后20min内监测的心率恢复到正常水平的时间。结果①不同HuTT结果比较：95％以上受试者在4min内心率恢复至正常水平，其中HUTT阳性组较HUTT阴性组恢复慢（94．8％vs 100％，X^2=23．5，P〈0．01）。②不同年龄比较：心率恢复至正常水平在2min内的儿童及青少年组较成人组多（90．6％VS85．7％，X^2=4．641，P〈0．05）；3min内的儿童及青少年组与成人组差异未见统计学意义（97．2％VS94．9％，X^2=3．131，P〉0．05）。③不同性别比较：心率恢复至正常水平在1min内男性多于女性（76．3％VS69．8％，X^2=4．932，P〈0．05）；2min内的性别比较差异无统计学意义（90．0％V888．3％，岩。=0．639，P〉0．05）。④不同反应类型比较：4min内心率恢复时间混合型较血管抑制型、心脏抑制型明显减慢（85．3％VS97．1％VS100％，X^2=23．5，P〈0．01）。血管抑制型与心脏抑制型差异无统计学意义（97．1％vs100％，X^2=0．149，P〉0．05）。结论95％以上受试者在HUTT结束后4min内心率恢复至正常，心率恢复时间受年龄、性别、HUTT结果及反应类型的影响。Objective To explore the time when the heart rate recover to a normal level after the head - up tilt table test （HUTT）. Methods Head - up tilt table test （HUTT） were performed in 919 patients in the Second Xiangya Hospital of Central South University from January of 2004 to May of 2011. Age 2 -74 years,mean age （ 18.4 ±14.0） years, 439 males, 480 females, Children and youth groups （ 〈 18 years） 646, adults group （ ≥18 years） 273, HUTT negative groups 439 and positive group 480, vasodepressor response type 380 and cardioinhibitor type 5 and mixed response type 95. We analysed the time when the heart rate recover to a normal level after the HUTT in 20 minutes＇monitoring. Results ①Comparing with different HUTT results： The patients whose heart rate recovered to a normal level within 4 minutes were more than 95%. The HUTT positive group recovered more slowly than the HUTT negative group within 4 minutes after HurFr （94. 8% vs 100% ,X^2 = 23. 5, P 〈 0. 01 ）.②Comparing with different age ： The amount of the patients in the children and youth groups was more than the adults group whose heart rate recovered within 2 minutes（90.6% vs 85.7% ,X^2 =4. 641 ,P 〈 0. 05 ） ; Children and youth differences adults group and found no statistical significance within 3 minutes （97.2% vs 94.9% , X^2 = 3. 131 ,P 〉0.05）. ③Comparing with different gender： The amount of thepatients in the male was more than the female who recovered within 1 minutes （76.3% vs 69.8%, X^2 = 4. 932 ,P 〈0.05）, but there was no significant differences between the male and the female whose heart rate recovered within 2 minutes（90.0% vs 88.3% , X^2 = 0.639 ,P 〉 0.05）. ④Comparing with different response types ： The heart rate recovery time within 4 minutes of the mixed response type was the slowest in the three. And The heart rate recovery time of the mixed response type was lower than the vasodepressor response type and the cardioinhibitor type （85.3% vs 97.1% vs 100%, X^2 = 23.5 ,P 〈 0.0
