Resume. The purpose of this investigation is to study the adequacy of the echocardiography method in small laboratory animals for performing acute pharmacological tests. In experiments on white mongrel male rats, a nonselective ß-adrenoreceptor agonist isoproterenol (20 μg /kg, i.v.) reduces the end-systolic and end-diastolic dimensions and volumes of the heart left ventricle, measured by echocardiography, and increases the shortening and ejection fractions, i.e. has a positive inotropic effect. Cardioselective ß1-adrenoblocker metoprolol (1 mg / kg, i.v.), on the contrary, increases the left ventricle sizes and reduces the shortening and ejection fractions, i.e. has a negative inotropic effect. Thus, the method of echocardiography in small laboratory animals can be used to conduct acute pharmacological tests.
