Article information

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.

Palabras clave:
nodo sinoatrial
arritmias

Farmacología

Sinus node dysfunction is an alteration in the impulse generation in the sinus node. Its main cause is the fibrous degeneration of the sinus tissue. Cases associated with seizures have multiple causes and are due to the cardio-depressant effects of anticonvulsants or its diluents. Likewise, there may be cases of bradycardia and asystole induced by epileptic discharges.

Here is presented the case of a female patient with status epilepticus who was treated with intravenous phenytoin and was previously receiving and developed sinus node dysfunction which was considered as a toxic side effect of her anticonvulsant medication.

Key words:
sinoatrial node
arrhythmia
nervous system
