| Abstract: | Intoxication with metaproterenol, a mainly beta-2 selective agonist, was diagnosed in a dog with tachycardia, tachypnea, weakness, vomiting, and a history of exposure to the drug. Electrocardiography and echocardiography disclosed sinus tachycardia with episodes of ventricular tachycardia and exuberant systolic ventricular function, respectively. Administration of the beta blocking drugs propranolol and atenolol led to resolution of the clinical signs. Excessive sympathetic stimulation caused by metaproterenol is an unusual intoxication in dogs. |
