The study demonstrates that domestic rats exhibit similar characteristics of sudden death during swimming stress as wild rats, including bradycardia and sensory/experiential dependence.

Replicates stress-induced sudden death in domestic rats; hypothesis-generating for psychosomatic bradycardia mechanisms before human translation.
Three reported charateristics of sudden death in the wild rat, (1) bradycardia, (2) decreased survival without whiskers, and (3) increased suvival with preexposure to the stressor, are demonstrated in the domestic rat. Differences in sudden death between wild and domestic rats are discussed as well as possible interpretations of the phenomenon.
