[ECG changes during [correction of dring] high G centrifuge training].
ECG of 47 healthy subjects, during G-training on the human centrifuge were recorded and analyzed. Training consisted of 4 G profiles and carried out in 6 d. Subjects were divided into 3 groups according to different anti-G equipment used. The results showed that: high incidence of arrhythmia (87%) was observed, and it increased with the increase of G level; subjects with R/S < 1 under +Gz environment, or HR sharply dropped immediately after the +Gz load have lower G-tolerance; incidence of arrhythmia is lower when advanced anti-G equipment was used.
