La disfunción del nodo sinusal consiste en una alteración en la generación del impulso en el nodo sinusal. Su principal causa es la degeneración fibrosa del tejido sinusal. Los casos asociados a convulsiones son multicausales y se deben a los efectos cardiodepresores de los anticonvulsivantes o de sus diluyentes; así mismo se pueden presentar casos de bradicardia y asistolia inducidos por las descargas epilépticas. Se expone el caso de una paciente con status epiléptico tratada con fenitoína endovenosa, quien recibía previamente carbamazepina y desarrolló disfunción del nodo sinusal considerada como un efecto secundario tóxico de su medicación anticonvulsivante.
