Arrhythmogenic epilepsy: an hypothesis

E L Pritchett, J O McNamara, J J Gallagher

    American Heart Journal
    |November 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    This study suggests that some arrhythmias, like paroxysmal supraventricular tachycardia (PSVT), may originate from neurological issues, specifically seizures. Treatment with antiepileptic drugs controlled symptoms in one patient.

    Area of Science:

    • Neurology
    • Cardiology
    • Clinical Electrophysiology

    Background:

    • Arrhythmias can significantly impact patient health and quality of life.
    • The neural origin of certain cardiac arrhythmias remains an area of active investigation.

    Observation:

    • Two patients presented with recurrent episodes of loss of consciousness, disorientation, and paroxysmal supraventricular tachycardia (PSVT).
    • One patient experienced neurological symptoms without concurrent tachycardia.
    • Standard electrophysiologic testing did not reveal abnormalities to explain the observed arrhythmias.

    Findings:

    • Electroencephalograms (EEGs) in both patients demonstrated epileptiform discharges, suggesting a neurological basis.
    • The findings indicate a potential link between seizure activity and cardiac arrhythmias.

    Implications:

    • This research suggests that arrhythmias may sometimes be a manifestation of underlying seizure disorders.
    • Further investigation into the neural mechanisms of arrhythmias is warranted.
    • Antiepileptic drug therapy, such as carbamazepine, may be a viable treatment option for select patients with neurologically-induced arrhythmias.
