72 patients (ages of 51+11), male: 66, female: 6 known or suspected coronary artery diseases (CAD), hospitalized in Department of Cardiology of hospital 108, underwent exercise electrocardiogram. Of the patients, exercise electrocardiogram was positive in 16 (22%). The clinical symtoms between negative and positive exercise electrocardiogram were compared. We found that: two important symtoms for indicating exercise electrocardiogram were compared. We found that: two important symtoms for indicating exercise electrocardiagram were typical angina pectoris (44%, p<0.05) and ST-T abnormalities on the electrocardiogram at rest (50%, p<0.1). Of the positive electrocardiogram patients, 9 were carried out of coronarography. Comparison with coronarography (stenosis> 50%), exercise electrocardiogram showed its sensitivity, specifycity and accuracy for diagnosis of were 100%, 50% and 66.7% (respectively).
