笔者对30名歼击飞行员用CM_1、CM_3、CM_5双极导联进行24h动态心电图(DCG)监测,结果心率在地面工作日与普通人基本相同,飞行中平均68±7次/min,最高为124±24次/min,最低54±6次/min,飞行后与地面工作日相应时间相同;未见心脏节律的明显变化;未监 测到T波改变。2例在高空特技飞行中ST段水平下移0.075～.0100mV,但活动平板运动试验阴性。笔者认为DCG适用于飞行员飞行中监测,特别对平时有症状的飞行员,可以提高诊断的准确性。
The authors conducted 24-hour ambulatory electrocardiogram (DCG) monitoring on 30 fighter pilots using bipolar lead CM_1, CM_3 and CM_5. The results showed that the heart rate was basically the same as that of ordinary people on ground working day with an average of 68 ± 7 beats / min and a maximum of 124 ± 24 beats / min, minimum 54 ± 6 beats / min, the same time as the ground working day after flight; no obvious change of heart rhythm; no change of T wave was detected. In the two cases, ST segment level decreased 0.075 ~ .0100 mV in altitude aerobatics, but the activity of treadmill exercise test was negative. I believe that DCG is suitable for pilots in flight monitoring, especially for the usual symptoms of pilots, can improve the diagnostic accuracy.
