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.
