Distinct differences in the three standard leads of the electrocardiograms were observed in both groups. These observations have been confirmed.3, 14 These studies have been extended in the present work by including the use of chest leads. In addition, experiments on dogs have been made in order to further interpretation of the results obtained in man.PROCEDUREElectrocardiograms were obtained on 65 healthy persons of both asthenic and pyknic builds and on 116 cardiac...Bibliography1.
