An Electrocardiographic Survey of the Aged

Abstract
In a short-term study, 38% of a group of hospital and clinic patients at least 75 years of age were found to have normal resting electrocardiograms. Other surprising findings were a higher incidence of atrial fibrillation than of atrial premature contractions, a relatively low incidence of acute or residual myocardial infarction, and a very low incidence of digitalis intoxication among the patients treated with this drug.
