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 ,风心病所致心律失常结果提示成都地区风心病患病率高于西藏地区
OBJECTIVE: To investigate the similarities and differences of arrhythmia distribution among people living in the hinterland of the Tibet Plateau and those living in the hinterland. Methods: 500 Han adults who migrated to Chengdu from the Tibetan Plateau were selected as the observation group and 500 adults of Han nationality in Chengdu were selected as the control group. The sampling population, sex, age and living community point Paired, through the diagnostic examination and electrocardiogram and / or ambulatory electrocardiogram to make the corresponding diagnosis of arrhythmia. Counting data were expressed in terms of number of cases and percentage. The data of two groups were tested by chi-square test. P≤0 0 5 was significant. Results: There was no significant difference in the total detection rate of arrhythmia between the observation group and the control group (P> 0.05), but not gender (P> 0.05). However, the detection rate of arrhythmia in the subgroup Group sinus bradycardia was higher than the control group (P <0 05), while sinus tachycardia was not as high as the control group (P <0 05). In the relationship between arrhythmia and disease, arrhythmia caused by rheumatic heart disease was more common in the control group (P <0.05), and was mainly atrial fibrillation. Conclusion: The total incidence of arrhythmia in the population of the Mainland who migrated to the interior of the Tibet Plateau is similar to those in the rest of the population in the Mainland. However, those with sinus bradycardia caused by hypoxia in the plateau showed that some people did not reverse their migration to the Mainland, but the prognosis was good. The prevalence of sinus tachycardia in the Mainland population is relatively high due to different types of diseases, but the prognosis is relatively poor; the relationship between arrhythmia and the disease is not completely consistent between the two groups. The arrhythmia caused by rheumatic heart disease indicates that the regional wind The prevalence of heart disease is higher than that in Tibet
