VALENCIA, Julián D.; RODRIGUEZ, Douglas E.; VALDES, Jaime F.  e  RUSSI, Yuli A.. Bradycardia and seizures: a multi-causal relationship. Rev. Colomb. Cardiol. [online]. 2014, vol.21, n.1, pp.48-51. ISSN 0120-5633.

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.
