title: [Comparative value of electrocardiographic criteria of myocardial ischemia in exercise tests].
abstract: Treadmill and isometric tests were carried out in 108 patients with coronary heart disease confirmed at coronary arteriography versus 51 healthy subjects. Among myocardial ischemia criteria depressed S-T segment came out as most reliable (probability of valid diagnosis greater than 90%), less significant was wave T inversion, wider wave R amplitude, painful syndrome (probability 70%). The rise and depression of oblique upward segment S-T, abnormal T amplitude proved inferior to the above signs (probability less than 50%). To achieve valid diagnosis of coronary heart disease and to assess its severity, exercise tests should produce reliable criteria of myocardial ischemia.
