Grand mal epilepsy as recorded during dynamic electrocardiography

Area of Science:

• Cardiology
• Neurology
• Clinical Medicine

Background:

• Epilepsy diagnosis requires careful differentiation from other conditions.
• Post-myocardial infarction patients are at risk for cardiac arrhythmias.
• Cardiac arrhythmias can manifest with neurological symptoms.

Observation:

• A patient with diagnosed epilepsy, post-myocardial infarction, underwent ambulatory electrocardiographic monitoring.
• The patient experienced an epileptic seizure during monitoring.
• The electrocardiogram (ECG) captured the seizure's characteristics and duration.

Findings:

• The documented seizure exhibited features consistent with cardiac arrhythmia-induced events.
• Cardiac arrhythmias can trigger epileptiform seizures via neural pathways or cerebral hypoxia.
• Such seizures can mimic true epilepsy, ranging from confusion to generalized convulsions.

Implications:

• This case highlights the importance of considering cardiac etiologies in seizure presentations, especially in post-MI patients.
• Ambulatory ECG monitoring is valuable for diagnosing arrhythmia-related seizures.
• Distinguishing cardiac-induced seizures from cryptogenic epilepsy is crucial for appropriate management.
