目的了解2010年克山病病区居民心电图异常程度,提出异常心电图指数概念,为量化心电图异常程度和克山病的防治提供依据。方法采用非概率抽样方法,对克山病病区居民进行人口学资料调查和临床检查,以《克山病诊断标准》(GB17021-1997)为诊断标准。结果此次调查13省共46 836人中,心电图异常人数为7 851人,异常率为16.8%。检出潜在型克山病患者802人,慢型克山病患者240人。克山病患者异常心电图以束支传导阻滞和T波和(或)ST段改变为主。慢型克山病患者异常心电图指数平均值(1.22±0.49)大于潜在型克山病患者(1.11±0.32)。结论此次调查的病区,心电图异常指数较高,提示病区居民还在受致病因素影响。
Objective To understand the abnormality of ECG of residents in Keshan disease in 2010 and to put forward the concept of abnormal ECG index to provide evidence for quantifying the degree of abnormal ECG and prevention and treatment of Keshan disease. Methods Non-probabilistic sampling method was used to investigate the demographic data and clinical examination of Keshan disease patients. The diagnostic criteria of Keshan Disease (GB17021-1997) were used as diagnostic criteria. Results Of the 46 836 people surveyed in 13 provinces, the number of abnormal electrocardiogram was 7 851, with an abnormal rate of 16.8%. There were 802 potential patients with Keshan disease and 240 patients with chronic Keshan disease. Keshan disease abnormal ECG with bundle branch block and T wave and (or) ST segment changes based. The average abnormal ECG index of patients with chronic Keshan disease (1.22 ± 0.49) was higher than that of patients with underlying Keshan disease (1.11 ± 0.32). Conclusion The survey of ward, ECG abnormal index higher, suggesting that ward residents are still affected by the risk factors.
