- Abstract
The observations of surface electromaps recorded at rest and during exercise in two examplative cases are reported: the first one deals with a normal man while the second refers to a patient suffering from an old inferior myocardial infarction with bouts of angina pectoris; these surface maps are compared with myocardial scanning also performed at rest and during exercise. Special attention is devoted to the possible relation of the above described, non-invasive, techniques to the anatomical description of coronary lesions as demonstrated by coronary angiography. A close relationship is found between the surface potential distribution pattern and the area of hypofixation observed on the scan as far as the presumed location of ischemic myocardial tissue is concerned.
