The excitation process in the electrocardiogram was telemetrically transmitted and recorded during psychic stress of 25 subjects aged between 17 and 56 years with healthy cardiovascular systems, during a standardized stunt flight program. The pulse rate profile showed a clearly marked sinus arrhythmia in the prestart phase and during the flight figures in which no acceleration force is in action, but essentially psychic stress alone. Corresponding to this sinus arrhythmia are distinct changes in amplitude of the P and T waves and the duration of the PQ interval, comparable to a changing sympathetic or vagus ECG. The behavior of the ST segment corresponds to that of ergometric stress, a horizontal or descending lower course was also observed in the younger subjects. In one case a 2:1 parasystole was observed during the change-over phase from higher to lower heart rates.
在一项标准化特技飞行项目中，对25名年龄在17至56岁之间、心血管系统健康的受试者施加精神压力时，通过遥测技术传输并记录心电图的兴奋过程。心率图谱显示，在起飞前阶段以及飞行过程中无加速力作用、仅存在精神压力的阶段，窦性心律不齐明显。与这种窦性心律不齐相对应的是，P波和T波振幅以及PQ间期持续时间有明显变化，类似于交感神经或迷走神经心电图的变化。ST段的表现与运动压力时的情况相符，在较年轻的受试者中也观察到了水平或下降的低位走势。在一例中，在心率从高到低的转换阶段观察到了2:1并行心律。
