Electrocardiographic Presentation at Ictal and Postictal Periods of Epileptic Seizure

Abstract

In epilepsy patients during video-electroencephalographic monitoring there are various electrocardiographic (ECG) changes during the epileptic seizure, sometimes remaining at postictal period as well. In the literature, various cardiac rhythm and conduction disorders are described, ventricular and supraventricular disorders, ST segment shifts. Some among these might be life-threatening, probably leading to unexplained sudden death in epilepsy. In the review, we focus on the most common ECG changes in patients with ongoing epileptic seizures.

Physiological and Biochemical Markers of the Sex-Specific Sensitivity to Epileptogenic Factors, Delayed Consequences of Seizures and Their Response to Vitamins B1 and B6 in a Rat Model

“…This view is confirmed by the two-way ANOVA pointing to the statistical significance of the factor of sex in the PTZ-induced changes ( Figure 1 B). In addition to the behavioral parameters, the potential cardiological risks of a seizure [ 27 , 28 , 29 ] may be estimated by ECG. As seen from Figure 1 B, the ECG assay does not reveal significant changes in the rats after the seizure.…”

“…According to clinical data, patients with epilepsy have increased risk of sudden death, most probably due to the seizure-perturbed heart rhythms characterized by ECG, hence the ECG analysis was employed to estimate the cardiological risks [ 27 , 28 , 29 ]. ECG was recorded using cutaneous electrodes (disposable silver chloride electrodes for recording ECG in newborns), attached to the right and left on the ventrolateral surface of the animal’s chest.…”
