[An analysis of dynamic ECG of 36 pilots]

24h dynamic electrocardiogram (DCG) of 36 healthy male fighter pilots, aged 25-35 years were recorded and analysed, then the data were compared with DCG of 55 normal subjects. The results showed that supraventricular arrythmias were more than ventricularones; both supraventricular and ventricular arrythmias of pilots were more than that of the control; the appearing rate of ST setment depression of pilots was higher.
