Analysis of 3 565 healthy pilots’rest recording ECGs using Minnesota code

摘要

ECGs of 3 565 clinically normal male pilots,aged from 21 to 51 years,were classi-fied and analyzed by Minnesota code.Among the 3 565 pilots,there were 1 315 coded pilots,making up 36.89％ of the total number.The results were as follows:abnormal Q/QS wave0.14％,electrocardial axis deflection 5.11％,high voltage of left ventricle 10.58％,chargedST-T segment 2.07％,atrioventricular conduction block 1.71％,intraventricular conductionblock 4.60％,arrhytmias 10.66％ and other abnormalities 13.04％.The research showed thatthere were various changes in the coded pilots,although no abnormal alteration of the cardio-vascular system was discovered by physical examination,the ECG exercise stress test and otherrelevant clinical tests.This suggests that most of ECG abnormalities in clinically normal pilotsare normal physiological and functional variations.
