Target Population
Care Setting

Key Highlights

  • SUDEP is a leading cause of death in epilepsy patients.
  • LQTS is a major cause of sudden cardiac death in adolescents and young adults.

Guideline-Based Recommendations

Diagnosis

  • Consider differential diagnosis between epilepsy and LQTS due to overlapping symptoms.

Management

  • Evaluate cardiac safety of anti-seizure medications in patients with epilepsy.

Monitoring & Follow-up

  • Monitor QT intervals in epilepsy patients to assess risk of cardiac events.

Risks

  • Patients with a history of epilepsy are at increased risk for fatal cardiac events in LQTS.

Patient & Prescribing Data

Genetic risk stratification may inform treatment and management strategies.

Clinical Best Practices

  • Integrate genetic testing in the assessment of patients with epilepsy and LQTS.
  • Conduct thorough cardiac evaluations in patients presenting with seizures.
