[Localization of infarction of the anterior and inferior myocardial wall by body surface mapping].
11 patients after anterior myocardial infarction and 7 patients inferior myocardial infarction were subjected to potentials mapping from 87 body surface electrode system. The reference group was made up by 15 healthy individuals. The analysis referred to isopotential and isointegral maps during the 20 ms and 40 ms of the QRS onset and for the entire QRS. It was stated that the occurrence of abnormal potential minimum might be the essential diagnostic criterion. In the case of anterior infarction, the abnormal negative potentials is located in the vicinity of the sternum, whereas in inferior infarction in right and lower part of the chest. The diagnostics of inferior infarction requires additional criteria, ventricular activation time maps especially.
