There is actually little evidence to support this view. Most of the studies which purport to show more electrocardiographic abnormalities in the later age groups are based on either "non-cardiac hospital patients" or on series of routine tracings of inadequately studied individuals. The careful study of Larsen and Skulason1avoided most of the sources of error of previous investigations. In a group of 100...Bibliography1. LARSENSKULASON KT: The normal electrocardiogram. I.
