Cross-Sectional (n=122,043)
In a large cohort of apparently healthy men, 4.72% demonstrated electrocardiographic abnormalities, providing age-stratified incidence rates.
ECG abnormalities in healthy men warrant cautious ECG interpretation; extends normative prevalence data but leaves screening utility open.
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.

Hiss et al. (1962) conducted a cross-sectional in Apparently healthy (n=122,043). Electrocardiogram screening was evaluated on Electrocardiographic abnormalities.
