Accuracy of exercise echocardiography to detect coronary artery disease in left bundle branch block unassociated with either acute or healed myocardial infarction.
To search for the value of treadmill exercise echocardiography in the detection of coronary artery disease in noninfarcted patients with left bundle branch block, we studied 35 patients (17 with coronary artery disease). We found high sensitivity, specificity, and accuracy (76%, 83%, and 80%, respectively).
