The American Journal of Cardiology, 1962
Abstract (1) We have observed a total of 59 cases of first degree heart block with a P-R interval 0.24 second or greater in a consecutive series of 19,000 fit, young aircrew applicants. None has been associated with proved organic heart disease. Of the prolonged P-R intervals, 85 per cent were reduced to within normal limits in the standing position.
