HEART CONDUCTION AND RHYTHM DISORDERS IN IKTAL EPILEPSY PERIOD: THE PREVALENCE AND PREDICTORS
Abstract
Aim. To assess the characteristics and prevalence of cardiac rhythm disorders in epilepsy patients during the iktal period, by long term ECG monitoring.Material and methods. To the study, 79 patients included, age 18 to 51 y. o. with confirmed diagnosis of focal epilepsy with continuing attacks regardless the antiepilepsy treatment. For rhythm disorder screening, all patients underwent implanting of subcutaneous ECG monitors.Results. Disorders of cardiac rhythm and conduction during the iktal period were found in 88,61% cases. Most prevalent were sinus tachycardia (59,5%, 47 cases), cardiac rhythm and conduction disorders (29%, 23 cases). In 9 cases (11,4%) there were no cardiac rhythm and conduction disorders registered. Also, the probable predictors found, of the disorders of cardiac rhythm in epilepsy patients. Patients gender, type of attacks, frequency, circadian specifics were the markers influencing the rate of iktal cardiac rhythm changes.Conclusion. Sinus tachycardia, rhythm and conduction disorders are registered in most of patients during the iktal period and significantly more common in males, the patients with bilateral tonic and clonic seizures, serial course of the attacks and in the patients with sleep-related seizures. Evaluation of antiepilepsy treatment influence on the prevalence of iktal rhythm and conduction disorders did not reveal significant difference for none of the drug groups. Also, there was no significant differences in comparison of the studied parameters for polyand monotherapy by anticonvulsants.
