目的 评价健康飞行人员的多组右胸导联心电图的特征,为飞行人员健康鉴定提供参考依据。方法 对210例健康飞行人员的常规、头胸、胸腹3种右胸导联心电图进行人工检测对比。结果 ①伪性Q波在头胸导联出现率最低,即V_1～V_(3R)无Q波,V_4～V_(5R)Q波占2％,V_(6R)占7％;②常规右胸、头胸导联V_(3R)的ST≥0.1mV,分别占8％和3％,V_4～V_(6R)的ST均在正常范围;③头胸导联V_1～V_(6R)的T波多数直立(85％～67％)。结论 健康飞行人员3种右胸导联心电图的变化规律可为有心室心肌梗死的诊断提供参考。
Objective To evaluate the characteristics of multiple groups of right chest lead ECG of healthy flight crew and provide references for the health assessment of pilots. Methods The routine electrocardiogram (ECG) of right chest lead of 210 healthy pilots were compared with those of right chest, chest and abdomen. Results ① The incidence of pseudo Q wave was the lowest in the leads of the head and chest, that is, there was no Q wave in V_1 ~ V_ (3R), 2% of V_4 ~ V_ (5R) Q wave and 7% of V_ (6R) , ST_0.1mV of V_ (3R) in head-chest lead were8% and3%, respectively, ST of V_4 ~ V_ (6R) were in the normal range; ③T wave of V_1 ~ V_ Most upright (85% ~ 67%). Conclusion The electrocardiogram changes of three kinds of right chest leads of healthy pilots may provide a reference for the diagnosis of ventricular myocardial infarction.
