摘　　要：目的:探讨飞行训练对战斗机飞行员HR、QTc、QTd的影响。方法:应用12通道同步心电图记录仪,对40名飞行员按不同分组测定飞行训练前后HR、QTc、QTd并加以对比分析。结果:飞行员HR飞后10 min、一次飞后10 min、二次飞后10 min、昼航后10 min、5G载荷飞后10 min、5 km飞后10 min与飞前比较差异有统计学意义(P<0.05);不同飞行场次、不同飞行强度、不同飞行载荷、不同飞行高度QTc、QTd飞前后无变化(P>0.05)。结论:HR的变化取决于飞行员对飞行应激的适应能力,与飞行负荷、飞行时间呈正相关性。Objective：To investigate the changes of HR、QTc、QTd at pre and postflight training for pilots.Methods：Using ECG recorder,HR、QTc、QTd were determined in different groups pre and postflight training to 40 pilots,and comparative analysis.Results：HR of postflight 10 min,1st Postflight 10 min,2nd Postflight 10 min,postflight-daily 10 min,＋5Gz postflight 10 min,5 km postflight 10 min were significantly higher than preflight（P0.05）;QTc、QTd of intensity of different flight,times of different flight,altitude of different flight,load of different flight pre and postflight were no significance（P0.05）.Conclusions：Changes of HR can depend on adaptive ability of the pilots to flight stress,and flight loads,flight time was a positive correlation.
