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.
心脏传导阻滞在成年马中是一种相对常见的心律失常。它可能是一种正常的生理现象，也可能具有病理意义。四匹在麻醉期间发生高度心脏传导阻滞的马驹，单独使用硫酸阿托品和支持性治疗无效。在治疗方案中加入盐酸多巴胺后，心脏传导阻滞得到缓解。
