Аннотация
Exercise testing (ET) and adenosine testing (AT) coupled with ECG were applied in 25 patients with old myocardial infarction. ET was positive in 8 (32%) and AT in 10 (40%) patients, the sensitivity of the latter being slightly superior to the former but inferior to the sensitivity reported in the literature for AT-echocardiography. One should also notice the positivity of AT-ECG in 6 (24%) patients, with negative or inconclusive ET, and the double product (DP) at ischemic threshold which was twice as low for AT-ECG as for ET-ECG, proving that AT induced ischemia by decreasing O2 myocardial input. It is concluded that AT-ECG is useful in myocardial ischemia detection in association with ET or in patients who cannot perform ET for different reasons.
