Electrocardiographic-Vectorcardiographic Alterations and Laboratory Findings in Experimentally Myocardial Infarcted Dogs


Abstract: In this study, significant degrees of changes (p<0.05) according to the size of the infarct area were detected in the 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 biventricular myocardial infarcted dogs. Left ventricular infarctions caused patologic Q wave, elevation in ST segment and rotation in the T wave, particularly in the I, aVL, V2, V3 and V10 leads, and right ventricular myocardial infarctions caused these 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.
