直立倾斜实验对晕厥患者的临床诊断价值——附110例病例分析

The Clinical value of Tilt Tast(TTT)to diagnose syncope-analysing of 110cases.

目的了解直立倾斜实验对晕厥患者诊断的临床价值。方法对110例不明原因晕厥患者进行直立倾斜实验的结果进行回顾性研究。结果110例患者中阳性79例,占71.82%;基础实验阳性20例,占18.18%;异丙肾上腺素诱发阳性59例,占53.64%。79例阳性患者中晕厥后心率、收缩压乘积≤9000mmHg.次/min者72例,占91.14%。结论(1)直立倾斜实验对血管迷走性晕厥的诊断有重要价值;(2)加用异丙肾上腺素可提高实验的阳性率;(3)心率、收缩压乘积有助于判断阳性结果;(4)直立倾斜实验可以作为诊断血管迷走性晕厥的首选方法。

Objective To evaluate the clinical usefulness of TTT to diagnose syncope.Method110patients with unexplained syncope,who received TTT were retrospectively studied.Results Totally,79cases were positive,the portion was71.82%.20positive cases in basal TTT group(18.18%);59positive cases in Isoproterenol TTT(53.64%).The patients,whose heart rate(HR)×systolic blood pressure(SBP)product≤9000mmHg.bpm were72(91.14%).Conclusion(1)TTT has significant diagnostic value to syncope,(2)HR×BSP≤9000mmHg.bpm suggested the presence of vasovagal syncope(VS),(3)The positive rate of Isoproterenol TTT Was higher than that of basal TTT,(4)TTT is prior to diagnose VS.[
