体位改变对飞行员频域心电图的影响

目的 探讨体位改变对飞行员频域心电图(FCG)的影响，为FCG指标在航空航天医监医保工作中应用提供依据。方法 对65名飞行员分别于平卧位、头低位、站立位与坐位4种不同体住下进行FCG检测，同步描记12导心电图、寻问主诉症状进行对照分析。结果 体位改变使得FCG的级别分布、异常指标等随体位改变而发生了相应的变化。变化程度大小依次为站立位、头低位、坐位和平卧位。这些变化与同步记录的12导ECG及被试者主观反应相一致。结论 FCG随体位改变对机体刺激强度不同发生了相应变化，FCG是一个能反应心脏功能状态的客观指标。

Effects of Body Position Changes on Frequency Domain Correlative Cardiogram in Pilots

Objective To study the effects of the body position changes on FCG in pilots so as to explore the possibility of using FCG as an indicator of medical monitoring and medical support. Method 65 pilots were examined in 4 different body positions, i.e. supine position, head down position, standing position and sitting position.Twelve channel routine electrocardiogram was recorded synchronously, and their complaints were also recorded. Result The grade distribution and abnormal cases of the FCG varied with the body positions. The orders of changing magnitude were: the standing position, the head down position, the sitting position and the supine position. The changes accorded with that of 12 channels routine ECG synchronously recorded and complaints of the subjects. Conclusion The FCG was an objective index representing the cardiac functional status.
