ABSTRACT
Objective To explore the Electrocardiography (ECG) changes of residents in Keshan disease area and the status of growth and decline of Keshan disease in Shaanxi Province. Methods Using stratified randomized sampling method,2 mild,2 moderate and 2 serious disease counties were selected respectively in 2005 and 2006. A total of 6 counties were sampled,2 villages,one with severe disease and one with mild,were selected from each sampled county. A total of 12 villages were selected. The clinical examination and ECG were conducted in 3-year old children of agricultural population of the selected villages. Results ECG of 5692 cases were performed in the selected 12 village in the 6 counties,in which 4917 cases showed normal electrocardiogram,up to 86.38% (4917/5692). Two hundred and fifty-two cases showed roughly normal electrocardiograms,up to 4.43%(252/5692). Five hundred and twenty-three cases had abnormal electrocardiogram,accounting for 9.19% (523/5692). Among them,the abnormal electrocardiogram rates in mild,moderate and serious disease areas were 7.07% (144/2036), 11.41%(167/1646) and 10.54%(212/2010),respectively. Atrioventricular block was the major abnormal electrocardiogram change,followed by arrhythmia,ST-T changes,and low voltage. One hundred and thirty-nine cases were confirmed as latent and chronic Keshan diseases. One hundred and thirty-one cases were latent Keshan, and detection rate was 2.30%(131/5692). Eight cases were chronic Keshan,and the detective rate was 0.14% (8/5692). Complete right bundle branch block [37.06% (63/170) ],ST-T changes [22.35% (38/170) ],multiple premature ventricular beats [12.94% (22/170)] were the major abnormal electrocardiogram change of Keshan patients. Conclusions Atrioventricular block and arrhythmia are the major abnormal electrocardiogram changes. Keshan disease incidences are controlled under a stable condition.
