Plain-English summary
Two dogs developed a sudden slow heart rate (bradycardia) during surgery while under isoflurane anesthesia after receiving a dopamine infusion to help with low blood pressure. The bradycardia was linked to a reflex response that can occur with this treatment. The situation was serious, but the dogs were monitored closely, and the veterinary team was able to manage the effects of the medication.

Abstract
Dopamine is a commonly used positive inotropic agent for the treatment of hypotension in small animals. Two dogs that had undergone surgery, under isoflurane anaesthesia, developed a sudden and profound bradycardia when a dopamine infusion was administered. Bradycardia was attributed to the activation of the Bezold-Jarisch reflex, an inhibitory reflex, characterised by bradycardia and hypotension.
