Clinically relevant arrhythmias are not linked to risk of sudden unexpected death in epilepsy


  • People with refractory focal epilepsy do not have clinically relevant arrhythmias that can be used as markers of risk for sudden unexpected death in epilepsy.

Why this matters

    Although postictal asystole is associated with sudden unexpected death in epilepsy, its low incidence precludes its use as a risk biomarker. The absence of postictal arrhythmias does not support the use of loop recorders in people at high risk of sudden unexpected death.
