Arrhythmogenic seizures: diagnosis by simultaneous EEG/ECG recording
Neurology
|October 1, 1985
Summary
Idiopathic seizures may indicate underlying cardiac issues. Comprehensive EEG and cardiac evaluations are crucial for patients with refractory epilepsy.
Area of Science:
- Neurology
- Cardiology
- Clinical Electrophysiology
Background:
- Epilepsy management often focuses on neurological causes.
- Refractory seizures necessitate thorough etiological investigation.
- Cardiac comorbidities can present atypically.
Observation:
- A young male patient presented with presumed idiopathic seizures resistant to phenytoin.
- An episode of unconsciousness revealed sick sinus syndrome.
- Seizures persisted despite pacemaker implantation.
Findings:
- Left temporal seizure focus identified.
- Combined electroencephalogram (EEG) and electrocardiogram (ECG) monitoring during a seizure revealed left temporal paroxysmal discharge.
- An ictal cardiac arrhythmia occurred concurrently with the seizure discharge.
Implications:
- Suggests a potential link between temporal lobe epilepsy and cardiac arrhythmias.
- Highlights the importance of integrated EEG and cardiac assessment in unexplained seizures.
- Recommends reconsidering the diagnostic approach for
