Abstract：Objective To compare the detection rates of early repolarization syndrome(ERS) by 12 lead ambulatory electrocardiography(AECG) and routine electrocardiogram(ECG), and to reveal the former's diagnostic value. Methods Retrospective analysis was made on 3 967 cases of 12 lead AECG data. The above two electrocardiographic examination methods were utilized in screening ERS, strictly according to diagnostic criteria. The differences of ST segment and T wave in two different lead connection methods were comparatively analyzed. Results By 12 lead AECG, 81 ERS patients were screened out of the enrolled candidates, with a detection rate of 2.04%. There were 73 males(90.12%) and 8 females(9.88%), and the difference between the proportion of males and females was statistically significant(P＜0.01). The detection rate of ERS in 31-45 years old age group was higher than that in other age groups. However, only 9 ERS patients were screened out by routine 12 lead ECG(detection rate 0.23%). Conclusion The detection rate of ERS by 12 lead AECG is higher than that by routine 12 lead ECG. Twelve lead AECG can reflect ECG features of the disease better, especially the relationship between characteristic changes of ST-T segment and patients' heart rate as well as rational symptom. Therefore, this method is clinically valuable in diagnosing ERS.
