A thallium stress test
performed in December 1996 indicated reversible ischemic disease involving the septal wall of the left ventricle and irreversible ischemic disease of the inferior wall of the left ventricular myocardium.
During this time several tests, including a thallium stress test
and an electrocardiogram (EKG) were done.
