Myocardial injury following acute abdominal hemorrhage and septicemia in a seventeen-month-old draft horse

Abstract

A seventeen-month-old draft horse gelding was presented with acute abdominal bleeding following castration. After two blood transfusions and medical treatment, clinical parameters stabilized, and the horse seemed to recover. Four days after admission, the horse suddenly developed tachycardia, tachypnea and pyrexia. Electrocardiography revealed paroxysmal monomorphic ventricular tachycardia related to myocardial injury. The horse recovered progressively after medical treatment and returned to normal sinus rhythm. In this case report, the importance to monitor for myocardial injury and cardiac arrhythmias after acute hemorrhage is highlighted.
