[Precordial electrocartography (mapping) in cardiac infarct].
After a detailed literature survey the authors share the results from the precordial electromapping with the registration of 30 points upon the chest in 34 patients with ischemic heart disease (30 with transmural infarction and 4 with intermediary syndrome). The following indices were followed up: sigmaST (the sum of the elevation of ST segment measured at 60 msec of the S deflection recording) and the index nST (the sum of the points with an elevation greater than 0.1 mV/1 mm). Both indices well correlate to the level of blood creatine phosphokinase, determined 24 hours after the examination. Due to the close degree of correlation dependence, the two indices are interchangable for the practice. The precordial electromapping reflects the degree of extent of the "myocardial hypoxia" as well as the degree of the disturbed biological activity of the tissues, affected by the myocardial infarction.
