目的 评价正常人的多组右胸导联心电图的特征。方法 对210例正常空勤人员的常规、头胸、胸腹3组右胸导联进行了检测对比。结果 ①伪性Q波在头胸导联(HC)出现率最低,即HC的V_(1～3)R无Q波,V_(4～5)RQ波占2％,V_6R占7％;②常规右胸、HC导联STv_3R≥0.1mV分别为8％和3％,STv_(4～6)R均在正常范围;③HC的Tv_(1～6)多数直立(85％～67％)。结论 正常人3组右胸导联心电图的变化规律为RVI的诊断提供依据。
Objective To evaluate the characteristics of multiple groups of right chest lead ECG in normal subjects. Methods 210 cases of normal crew members routine, head and chest, chest and abdomen, right chest lead three groups were tested and compared. Results ① The incidence of pseudo-Q wave was the lowest in head-chest lead (HC), that is, there was no Q wave in V_ (1-3) R of HC, V_ (4-5) RQ wave was 2% and V_6R was 7%; Conventional right chest, HC lead STv_3R ≥ 0.1mV were 8% and 3%, STv_ (4 ~ 6) R were in the normal range; ③ HC Tv_ (1 ~ 6) most of the upright (85% to 67%). Conclusion The changes of right chest lead electrocardiogram in normal subjects provide the basis for the diagnosis of RVI.
