摘　　要：目的:探讨飞行员心电图U波的特点及临床意义。方法:对空军某部全体飞行人员261例和地勤人员254例体检心电图进行分析,并对其在不同心率及血压情况下的心电图U波特点进行比较分析。结果:飞行员中U波普遍出现,其出现率高达85.4%,其异常U波发生率明显高于对照组(P<0.01);心率≤80次/m in对飞行员U波的出现率及U波电压影响不大,而心率>80次/m in时U波出现率明显减少(P<0.01),U波电压明显降低(P<0.01);随着血压的升高,异常U波发生率明显上升,U波电压则有下降趋势。结论:飞行员中U波普遍出现,异常U波发生率较高,飞行员心电图异常U波出现与高血压病有关。AIM： To explore the characteristics and clinical significance of electrocardiogram （ECG） U wave in pilots. METHODS： PE cardiograms of 261 pilots were analyzed and the ECG U waves under different heart rates （HR） and different blood pressures were compared. RESULTS： U wave was observed in most pilots （85.4%） and abnormal U wave rate was significantly higher than in the control group （P〈0.01）. HR ≤80/min had little influence on U wave and U wave voltage, but HR 〉80/min markedly reduced U wave and U wave voltage （both P〈0.01）. The rate of abnormal U wave increased and U wave voltage decreased with the elevation of blood pressure. CONCLUSION： U wave appears in most pilots and abnormal U wave rate is high. Abnormal U wave is related to hypertension.
