Prognostic impact of misdiagnosis of cardiac channelopathies as epilepsy.

ABSTRACT:

Introduction

Cardiac channelopathies are a frequent cause of sudden cardiac death (SCD) and often manifest with convulsive syncope, leading to a misdiagnosis of epilepsy. We aim to evaluate the clinical impact of epilepsy misdiagnosis in a cohort of patients with cardiac channelopathies.

Methods

Fifty probands/families with a cardiac channelopathy were included.
