Interictal heart rate in patients with epilepsy.
2016
Abstract Electrocardiographic abnormalities in patients with epilepsy are related to the presence of discharges in central autonomic structures and the effect of antiepileptic drugs. These patients are at risk for sudden unexpected death, and cardiac arrhythmias are one of the most probable causes related to it. The heart rate (HR) assessment recorded on electrocardiography (ECG) in the interictal period in patients with newly diagnosed and previously treated epilepsy, depending on the type of changes in electroencephalography (EEG) and the treatment option. Fifty patients with epilepsy were enrolled in the study: 22 comprised a non-treated patient (NTP) group with newly diagnosed epilepsy and 28 comprised a treated patient (TP) group that had been treated for more than 2 years. Resting ECG and EEG were performed in all patients. A significantly higher HR was recorded in the TP group compared to the NTP group (80±13 vs 67±15 bpm, p=0.00006). The tendency to higher HR was observed in polytherapy patients, carbamazepine patients and in patients with a focus in the right hemisphere. There is a relationship between the presence of the disorders related to bioelectric activities of the brain and the heart, therefore the ECG should be periodically monitored in epileptic patients.
