The study was undertaken to assess the concordance of increased serum myocardial enzymes and myocardial injury with certain aberrations in electrocardiograms of dogs. Labrador Retriever dogs aged between 5 to 10 years and showing symptoms of cardiac problems like nocturnal coughing, exercise intolerance, cyanotic mucus membrane, inappetance, edema etc were considered for the study and apparently healthy Labrador Retriever dogs aged between 5 to 10 years having no history of cardiac disorders were enzymatically screened to get control values. Electrocardiographic alterations like tall T waves were associated with increased serum levels of CKMB (Creatine Kinase MB isoenzyme), LDH (Lactate Dehydrogenase) and AST (Aspartate Aminotransferase) while ECG aberrations like ST segment abnormalities and arrhythmia were associated with increased levels of CKMB and LDH in the serum. Our study concluded that myocardial infarction might be the reason behind certain ECG findings which are often believed to be of non-ischemic origins.
