Summary
A boy experienced seizures after injections, possibly due to neurocardiogenic syncope. His ECG showed asystole, leading to a generalized seizure, but tilt-table tests were inconclusive for this epilepsy case.
Area of Science:
- Neurology
- Cardiology
- Pediatrics
Background:
- Epileptic disorders can present with diverse etiologies.
- Neurocardiogenic syncope is a potential cause of transient loss of consciousness.
- Understanding seizure triggers in pediatric patients is crucial for diagnosis.
Observation:
- A 10-year-old boy presented with recurrent episodes of syncope following medical procedures (injections).
- During venipuncture, electrocardiography (ECG) revealed a 6-second asystole.
- Simultaneously, electroencephalography (EEG) demonstrated generalized seizure activity with focal clonic jerks and theta waves.
Findings:
- The observed asystole followed by generalized seizure suggests a link between cardiac events and neurological manifestations.
- Electrocardiography and electroencephalography recordings captured the critical event, correlating cardiac asystole with seizure onset.
- Negative tilt-table testing indicated that vasovagal syncope might not be the sole explanation for the patient's presentation.
Implications:
- This case highlights the importance of considering neurocardiogenic syncope as a potential cause of seizures in children.
- Integrated cardiovascular and neurological monitoring is essential for diagnosing complex cases of syncope and seizures.
- Further investigation may be warranted to elucidate the precise mechanism linking asystole to seizure activity in this patient.
