BACKGROUND: The relationship between seizure activity and arrhythmias is not well established. Sinus tachycardia is commonly seen post seizure. Bradyarrythmias leading to seizure activity is rarely reported in the literature thus far. CASE PRESENTATION: A 62-year-old lady presented with nocturnal seizures and was subsequently started on oral anti-convulsant with no relief of her symptoms. Further investigations led to outpatient ambulatory ECGs which showed marked sinus bradycardia prior to seizure activity and post seizure atrial fibrillation with fast ventricular rate. The patient was commenced on oral anticoagulant and beta blocker for ventricular rate control in view of atrial fibrillation. A backup dual chamber permanent pacemaker was implanted to treat the bradycardia. The patient became seizure free since the implantation of permanent pacemaker. CONCLUSION: This case stresses the importance of investigating and treating cardiac arrhythmias underlying seizure activity.
