Electrocardiogram analysis of 130 cases of chronic Keshan disease in Inner Mongolia / 中华地方病学杂志

ABSTRACT

Objective To observe and analyze the electrocardiogram (ECG) characteristics of patients with chronic Keshan disease and explore the influence of health management on ECG of chronic Keshan disease.Methods ECG data of 130 patients with chronic Keshan disease who were involved in the health management program for Keshan Disease from 2012 to 2014 in the area of Inner Mongolia were analyzed retrospectively (57 were males and 73 were females,aged 51.2 ± 11.5).The survey indexes include general condition,ECG examination before and after implementing the health management program.Results There were abnormal ECG in 130 patients with chronic Keshan disease before implementing the health management program.Among them,87 cases (66.9％) had arrhythmia,74 cases (56.9％) had widening of QRS wave group,56 cases (43.1％) had ST-T changes,51 cases (39.2％) had atrioventricular hypertrophy,9 cases (6.9％) had abnormal Q wave and 5 cases (3.8％) had prolonged Q-T interval.After implementing the health management program,there were 64 cases (49.2％) of arrhythmia in abnormal ECG,48 cases (36.9％) with widening of QRS wave group,40 cases (30.8％) with ST-T changes and 31 cases (23.8％) with atrioventricular hypertrophy,which were significantly lower than those before implementing the health management program (x2 =8.36,10.44,4.23,7.13,P ＜ 0.05).Conclusions The ECG of patients with chronic Keshan disease is varied,among which arrhythmia,QRS wave group prolongs,ST-T changes,atrioventricular hypertrophy are the most common.Health management of patients can make the detection rate of common abnormal changes of ECG decrease obviously.
