Abstract：Objective To study the relationship between electrocardiogram(ECG) characteristics and prognosis of early repolarization syndrome(ERS) among community physical examination population. Methods A community population of 6 612 was enrolled in our study. These research objects were aged between 18 and 75 years old with complete ECG and clinical data in the remote ECG examination in Binhu Hospital of Hefei City. The patients were diagnosed and classified according to the ECG diagnostic criteria of ERS; their biochemical indicators and clinical data were recorded. Results There are 185 cases with ERS(2.8%) and 6 427 cases without ERS; in the ERS group, the average heart rate is significantly lower than that in the non-ERS group while QT interval and QTc are both significantly prolonged(P＜0.05). ERS subgroup analysis indicates that QT interval of the population with amaurosis history is significantly longer than that of the population without amaurosis history(P＜0.05). There is statistically significant differences between the two groups in aspects of sex, history of smoking, history of amaurosis, body mass index, history of coronary heart disease, diabetes and cerebral infarction, and total cholesterol and high density lipoprotein(P＜0.05). Regression analysis suggests that heart rate, PQ interval, QRS duration, QT interval and QTc are risk factors for ERS (P＜0.05); age, sex, and histories of hypertension, diabetes and coronary heart disease are not risk factors for ERS(P＞0.05). Conclusion Among the ERS patients in the community physical examination population, the heart rate is significantly slower, and QT and QTc intervals are significantly prolonged; the incidence of amaurosis significantly increases which is apparently correlated with QT interval. P-wave duration, PQ interval, QRS duration, and QT interval and QTc may be risk factors for ERS.
