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.
