Upon submersion, the domestic duck normally displays a prompt but modest cardiac retardation, which, after a short delay, is reinforced into a pronounced state of bradycardia. The present study has revealed that arterial asphyxia is a prerequisite for the reinforcement of the initial slight bradycardia.
在浸入水中时，家鸭通常会迅速但适度地出现心脏迟缓，经过短暂延迟后，这种迟缓会加剧为明显的心动过缓状态。本研究表明，动脉性窒息是最初轻微心动过缓加剧的先决条件。
