Overview
Brief Summary
Seizure-related cardiac arrhythmias are one of the possible causes of sudden unexpected death in epilepsy (SUDEP). Identification of these patients is challenging because cardiac rhythm disturbances could emerge only during seizures. Furthermore, patients could have transitioned sinus or AV node blocks which could cause syncopes with brady-related seizures which could be treated as epilepsy-related seizures. Implantable loop recorders have an ability to recording single-channel ECG for up to 36 months which give an ability to detect these heart disturbances.
The purpose of this study is to look the incidence and types of arrhythmias which occur in 150 patients with hard-to-treat partial seizures and secondarily generalized seizures

Outcomes
Primary Outcomes
Identification of a dysrhythmia
Time Frame: 3 years or until the end-of-battery life of Reveal XT, whichever came first
A dysrhythmia will be defined as either * asystole of ≥6 s * sinus bradycardia of ≤40 bpm during physical activity * 2nd or 3rd-degree AV-block * sinus tachycardia of ≥120 bpm * nonsustained and sustained monomorphic VT of ≥170 bpm * polymorphic VT * atrial fibrillation/flutter
Secondary Outcomes
- The number of patients who will have receive the permanent pacemaker at the end of the study.(3 years or until the end-of-battery life of Reveal XT, whichever came first)
