摘要
目的 :探讨西藏高原移居内地人群与世居内地人群心律失常分布的异同特征。方法 :选择从西藏高原移居成都市的汉族成人 5 0 0例为观察组 ,世居成都市的汉族成人 5 0 0例为对照组 ,就两组抽样调查人群数、性别、年龄及居住社区点进行配对 ,通过问诊查体及心电图和 /或动态心电图作出相应心律失常诊断。计数资料以病例数及百分比表示 ,两组数据采用卡方检验 ,P≤ 0 0 5有显著意义。结果 :观察组与对照组心律失常总检出率无明显差异(P >0 0 5 ) ,且与性别无关 (P值均 >0 0 5 ) ;但从检出的心律失常亚组人群中观察组窦性心动过缓高于对照组 (P <0 0 5 ) ,而窦性心动过速又不如对照组高 (P <0 0 5 )。心律失常与病种关系中 ,风心病致心律失常以对照组多见 (P <0 0 5 ) ,且主要为心房颤动。结论 :西藏高原移居内地人群心律失常总发生率与世居内地人群机遇相当 ,然而高原低氧环境致窦性心动过缓者显示部分人群并不因移居内地而逆转 ,但预后较好 ;世居内地人群窦性心动过速者因病种不同而发生率相对较高 ,但预后相对要差 ;心律失常与病种关系两组分布并不完全一致 。
Objective:To inquire into characteristics of cardiac arrhythmia in the population of Tibet plateau migration with flatland population.Methods:The object group is plateau migration population and the control group is flatland population.Two groups were both from the same communities of Chengdu cyty and were matched by sex and age. The reference standard of diagnosis in cardiac arrhythmia depends on ECG and/or DCG.Chi-square tests were used to analyze categorical variables.Results:The total prevalence of cardiac arrhythmia was of no difference between two groups(P>0 05),and was not relative with sex(P>0 05).The prevalence of sinus bradycardia was greater in plateau migration population than that of flatland population (P<0 05).The prevalence of sinus tachycardia was greater in flatland population than that of plateau migration population(P<0 05).Conclusion:The sinus bradycardia is largely not reversible in plateau migration population after they returned flatland,but some of their prognosis were better.And the prognosis of sunus tachycardia in flatland population were not better.
