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.
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.
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.
The FCG was an objective index representing the cardiac functional status.
