Electrocardiographic-vectorcardiographic alterations and laboratory findings in experimentally myocardial infarcted dogs.

摘要

Significant degrees of changes (P < 0.05) according to the size of the infarct area were observed in haematological (erythrocyte sedimentation rate and leukocyte count values increased), biochemical (LDH and CK-MB levels increased) and electrocardiographical (increase in heart frequency and single or multiple focuses of ventricular arrhythmias) findings in a total of 21 experimentally left-, right- and bi-ventricular myocardial infarcted dogs. Left ventricular infarctions resulted in pathologic Q waves, ST segment elevation and T wave rotation, particularly in the I, aVL, V2, V3 and V10 leads; right ventricular myocardial infarctions led to similar changes particularly in the V1, V4 and V5 and partially in the III and aVF leads, and left axis deviation occurred even in individuals with small areas of infarction.
