A dog was suspected to be afected with idiopathic myocardosis in the clinical examination. When it was subjected to cardio-echography (CEG), it exhibited an increase in volume of the left ventricle, the left cardiac hypofunction, and a decrease in the ability of cardiac muscle to contract. Therefore, a diagnosis of congestive myocardosis was made in it. The parameters useful for the diagnosis of this disease by CEG were the volume of the left ventricle, the expelled fraction, the average reduction rate of the left intraventricular circumference, the amplitude of movement of the posterior wall of the left ventricle, the velocity of contraction of the posterior wall, the rate of inflow at diastole, and the rate of dilatation of the posterior wall.
