Plain-English summary
In this study, four young horses (foals) developed a serious heart condition called advanced atrioventricular heart block while they were under anesthesia. This condition can sometimes happen in adult horses and may be normal or a sign of a problem. The foals did not improve with standard treatments, including a medication called atropine sulfate. However, when dopamine hydrochloride was added to their treatment, their heart blocks resolved. This shows that dopamine hydrochloride can be effective in treating this condition in foals during anesthesia.
Abstract
Heart block is a relatively common arrhythmia in the adult horse. It may be a normal physiologic phenomenon or it may have pathologic implication. Four foals in which advanced heart block developed during anesthesia were unresponsive to atropine sulfate and supportive treatment alone. Resolution of the heart blocks was achieved after the addition of dopamine hydrochloride to the therapeutic regimen.
