title: A simplified method of electrocardiogram interpretation.
abstract: A modified step test is described, suitable for office use with the performance of the effort electrocardiogram. The results of haemodynamic changes are briefly presented and the results of measurement of 104 ECGs are tabulated and graphed. It is shown that by using ECGs taken 6 minutes after effort with lead V6 and by measuring the slope angle of the S-T segment, all abnormal subjects can be distinguished from at least 95% of normal subjects. The presence of a plane segment plus an S-T slope angle of less than 6,5 degrees will totally separate normal subjects from those with myocardial ischaemia. The patient's history will usually be found to accord with the above.
