[Complex evaluation of the extent of myocardial infarction based on precordial ECG cartograms, myoglobin level and the indicators of creatine kinase and LDH activities in the blood]

Abstract

Good correlation between the size of necrosis, as measured by precordial cartograms of 35 ECG leads, and blood CPK and LDH activity and myoglobin levels was demonstrated in 21 myocardial infarction patients. Myoglobin measurement is particularly informative for early diagnosis of myocardial infarction and the assessment of the size of necrosis. A formula is proposed for the estimation of the size of necrosis on the basis of variation in R waves from 35 ECG leads.
