目的:分析体检人群中发生早期复极者的心电图特征.方法:以2020年1月至2021年1月49236例于我院进行健康体检的检查者为研究对象,所有患者均为常规健康检查,并分析受检人群中心电图早期复极检出率、心电图特征及不良症状发生情况.结果:49236例受检者早期复极总检出率为2.95％(1452/49236),与女性群体比较,男性群体早期复极检出率明显升高,且随着年龄的增长,早期复极检出率明显降低(P＜0.05).与对照组(健康人群)比较,早期复极组受检者心率变慢,Q-T间期缩短,QRS时长、TpTe间期则明“,”Objective:To analyze the electrocardiogram characteristics of patients with early repolarization in physical examination population.Methods From January 2020 to January 2021, 49,236 examiners who had physical examination in our hospital were selected as the research objects, and all patients had routine physical examination. The detection rate of early repolarization of electrocardiogram, ECG characteristics and adverse symptoms were analyzed. Results The total detection rate of early repolarization in 49236 subjects was 2.95％ (1452/49236).Compared with the female population, the detection rate of early repolarization in male population was significantly higher, and with the increase of age, the detection rate of early repolarization was significantly higher. Compared with the control group (healthy people), the heart rate in the early repolarization group was slower, the Q-T interval was shorter, and the QRS duration and TpTe interval were significantly longer (P＜0.05). The followup results showed that the incidence of chest pain, palpitation and shortness of breath was 2.20％ (32/1452),among which male patients aged 31-50 years accounted for the highest proportion. Conclusion Early repolarization mostly occurs in young male population, and its electrocardiogram is obviously different from that of healthy people. Clinical diagnosis of early repolarization can be timely and accurately based on the characteristics of electrocardiogram changes, so as to prevent cardiovascular diseases.
