摘　　要：目的探讨高原世居藏族DC的变化规律及其临床意义。方法比较西宁地区(海拔2295米)和玉树地区(海拔3681米)不同海拔藏、汉族心率减速力以及24小时最慢心率、平均心率、最快心率的差异性,及多发病与心率减速力的相关性,了解健康及患病组人群迷走神经张力高低的差异性。结果在高原地区世居藏族中,多发病组的DC值与对照组比较明显减小,差异均有统计学意义(P<0.01),健康对照组DC值偏高。结论高原地区临床应对患者行DC常规检测,可以直接量化患者迷走神经张力的高低,利于及时采取适宜干预措施,行双向预后评估,利于分层预警,减少猝死发生率。Objective To investigate the clinical significance by observing and analyzing the changes of deceleration capacity（ DC） in athnic Tibetan at high altitude. Methods Compare the difference of slow heart rate and 24 hours heart rate by slowest,mean,fastest of Han and Tibetan people between Xining with Yushu area.The relation of DC with frequently-occurring disease and of high or low with vagus nerve tension between health and patient in altitude were studied.Results There was statistical significance on DC with frequently-occurring ethnic Tibetan patients compared with control in high altitude area.Conclusion Dealing with patients＇ s DC usually can quantitate the high or low vagus nerve tension directly in high altitude and to take intervention measures in time.Doing Two-way prognosis＇ s assessment can quantitate layered alert and reduce the incidence of sudden death.
