目的初步了解我国健康人高位右侧胸前导联 Brugada 心电图征发生率及其意义。方法对1005例健康体检者进行病史询问、体格检查、X 线胸片、标准12导联和第二肋间右侧胸前导联心电图检查,按照欧洲心脏病学会制定的标准筛选 Brugada 心电图征。结果排除4例器质性心脏病和心律失常患者后,共1001例(男877例,女124例)人选,年龄17～75(28.3±14.8)岁。标准导联心电图检查发现5例2型 Brugada 心电图征(0.5%),第二肋间右侧胸前导联心电图检查发现47例 Brugada 心电图征(4.70%),均为男性(2型40例,3型7例)。无不明原因晕厥或黑矇史,无猝死家族史。结论对于症状不典型者,依据标准导联或高位右侧胸前导联2型或3型 Brugada 心电图征诊断 Brugada 综合征要慎重。
Objective To understand the incidence and significance of Brugada’s electrocardiogram sign on the right chest lead in healthy people in China. Methods A total of 1005 healthy subjects underwent physical examination, physical examination, X-ray, standard 12-lead and second intercostal right chest thoracic electrocardiogram. The Brugada electrocardiogram was screened according to the criteria established by the European Society of Cardiology. Results After excluding 4 patients with organic heart disease and arrhythmia, a total of 1001 patients (877 males and 124 females) were selected, aged from 17 to 75 (28.3 ± 14.8) years. Five cases of type 2 Brugada electrocardiogram (0.5%) were found on standard lead electrocardiogram (ECG), and 47 cases of Brugada electrocardiogram (4.70%) were found on the second intercostal right chest lead electrocardiogram. All were male (type 2 40 cases, 3 type 7 cases). No reason of unknown syncope or dark history, no sudden death family history. Conclusions For patients with atypical symptoms, it is prudent to diagnose Brugada syndrome based on standard leads or upper right thoracic lead type 2 or type 3 Brugada.
