【摘要】 目的 对基础直立倾斜试验中的不同血流动力学反应进行总结分析。方法 选择443例晕厥或头晕或走路不稳患者在安静环境空腹进行基础直立倾斜试验持续监测心电和血压，观察其血压、心率变化。结果共443例患者进行基础直立倾斜试验，其中阴性312例（70%）、直立性低血压66例（15%）、血管迷走性晕厥14例（3%）、体位性心动过速15例（4%）、直立性高血压36例（8%）。直立性低血压中经典型24例（36%），延迟型29例（44%），初起型8例（12%），进展型5例（8%）。结论 在临床进行短时基础直立倾斜试验的存在不同类型血流动力学反应，可对直立性低血压各亚型细致观察，较好反映自主神经系统对心血管的调节。更多还原

【Abstract】 Objective To study the different hemodynamic reaction patterns displasyed over the course of basic head-up tilt table tests in clinic patients. Methods Total 443 patients underwent basic head-up tilt table test, who were fasting more than 4 hours. The changes of blood pressure and heart rate were recorded. Results Among 443 patients who took the basic HUTT tests, 312 patients(70%)had negative reactions,66 patients(15%) were orthostatic hypotension(OH), 14 patients(3%)had vasovagal responses, 15 patients(4%) were orthostatic tachycardia syndrome,36 patients were orthostatic hypertension. Among OH patients, 24 patients(36%) were classical type of OH, 29 patients(44%)were delayed OH, 8 patients(12%) were initial OH, and 5 patients(8%) were progressive type of OH.Conclusions There are different hemodynamic reaction patterns in basic head-up tilt table tests. With careful observation in the different hemodynamic reactions in orthostatic hypotension, we can estimate the autonomic function in cardiology.更多还原
