The exercise electrocardiograms of 255 asymptomatic men were analyzed for changes in R wave amplitude and ST segments. The results were correlated with findings at cardiac catheterization. There were 65 men with coronary artery disease and 190 normal subjects. R wave amplitude changes were evaluated in bipolar leads X, Y and Z. The predictive value of an abnormal ST segment response for detecting disease was only 29%. This value was improved to 42% using R wave amplitude changes with a… CONTINUE READING
