Among the causes for sudden death in epilepsy, cardiac dysfunction has been an area of interest. Based on this, the aim of our study was to evaluate the heart rate (in vivo and in vitro) and ventricular pressure in vitro of rats with epilepsy induced by pilocarpine. Adult male Wistar rats (n=6) were given pilocarpine hydrochloride to induce status epilepticus. Control rats (n=6) received saline solution instead pilocarpine. Our results showed significant differences in the mean of heart rate in vivo between the groups. In contrast, we did not find differences during in vitro experiments. Our results suggest a central nervous system modulation on the heart, which could explain the sudden unexpected death in epilepsy.
