Abstract
A cardiographic study of the diagnosis of coronary heart disease in the presence of pulmonary disease has been made in 212 miners, analysing the cardiograms subjectively and by discriminant analysis against the autopsy evidence. A correct classification in all groups of 71.5% was obtained by the standard subjective study compared with 54.7% by discriminant analysis. Coronary heart disease in the presence of pulmonary disorder was noted in 69.5% by standard methods compared with 59% by discriminant analysis. The limitations of both methods are discussed.
