[Comparison of precordial electrocartography with pathologicoanatomic data on 20 patients with recent myocardial infarct].

In 20 patients with recent myocardial infarction, that died till the 40th day after the onset of the disease, a comparison is made of the data from the pathologoanatomical findings with the indices from the precordial electromapping. The changes in the ST segment of the precordial electromapping correlate, to a significant extent, to the weight of the infarction zone in patients with interior site of the myocardial infarction (sigmaST r = 0.89, p less than or equal to 0.01; nST r = 0.62, p less than or equal to 0.01). The indices from the precordial electromapping characterizing the changes in depolarization, are with a considerable less degree of correlation dependence to the weight of the enfarcted zone in the same patients (nQS r = 0.62, p less than or equal to 0.62, p less than or equal to 0.05; sigmaAR r/0.45, p less than or equal to 0.05). In patients with posterior and/or inferior site of the infarction the correlation dependence to the indices from the precordial electromapping is less manifested.
