Motor-car Driving and the Heart Rate

Abstract

Motor-car driving in London traffic may be associated with an increased heart rate, which is very rapid in certain persons with normal cardiovascular systems. ST-T changes in the electrocardiograms occurring at the same time seem to be related to anxiety rather than the tachycardia. Even more rapid heart rates may develop in certain drivers before and during competitive motor-racing. © 1967, British Medical Journal Publishing Group. All rights reserved.
