Samenvatting
A study of drivers on street and highway is in progress which involves in-car monitoring of the electrocardiogram for analysis of heart rate. Computer analysis of the in-car tape recording provides information to derive mean heart rates, standard deviation and coefficient of variation. These may offer some correlation with so called personality profiles. The principal outcome of the study is an awareness that much more information may be available from analysis of heart rate than has been recognized. It seems probable that analysis of heart rate in the manner described may prove useful in a comparison of activities and individuals.
