Cardiovascular responses of sports-pilots to aerobatic maneuvers have been inadequately studied. However many Soviet and foreign authors believe that acceleration effects may seriously deteriorate pilot performance. Our study has shown that cardiovascular changes are to maintain the necessary level of blood pressure in brain and eye arteries. During exposure to +Gz heart rate may be as high as 160 beats/min while during exposure to -Gz it may be as low as 60 beats/min. Pulse photoplethysmography recorded inflight has shown that during exposure to +Gz its amplitude decreases until pulse oscillations disappear, suggesting the development of visual disorders. Pulse photoplethysmography has revealed cardiac arrhythmias in the form of extrasystoles in some pilots. It has also been demonstrated that during flight cardiac arrhythmias can be best detected with the aid of correlation rhythmography.
运动飞行员对特技飞行动作的心血管反应尚未得到充分研究。然而,许多苏联和外国作者认为,加速度效应可能会严重降低飞行员的表现。我们的研究表明,心血管变化是为了维持脑动脉和眼动脉的必要血压水平。在承受+Gz时,心率可能高达160次/分钟,而在承受-Gz时,心率可能低至60次/分钟。飞行中记录的脉搏光电容积描记法显示,在承受+Gz时,其振幅会降低,直到脉搏振荡消失,这表明出现了视觉障碍。脉搏光电容积描记法还揭示了一些飞行员出现早搏形式的心律失常。研究还表明,在飞行过程中,借助相关心律描记法能够最好地检测出心律失常。
