Abstract
When examined by electrocardiography a 6-year-old male Boxer dog showed a first-degree atrioventricular block, ventricular premature beats, and ventricular tachycardia. In it, phonocardiography, radiography, and blood examination suggested myocardial disease. Echocardiography reveal that the ratio of the thickness of the ventricular septum to that of the posterior left ventricular free wall was 1.5. Mitral valve echo indicated an anterior systolic movement. These echocardiographic findings were considered specific enough to be important parameters in making a diagnosis of canine hypertrophic cardiomyopathy.
