Electrocardiograms on 122,043 apparently healthy male subjects aged 16 years to over 50 years have been studied. Of this group 5,773 subjects (4.72 per cent) had electrocardiographic abnormalities. The more common abnormalities were expressed in terms of rate per thousand subjects for each 5-year age group. This provides a means of relating incidence to age. Each abnormality and its clinical significance is discussed. In 54,668 subjects incidental findings such as notched P waves, amplitude, and wave forms were tabulated.
