Cardiac Arrhythmias Increase Mortality and Morbidity in Children with Seizure Disorders

According to a recent study published in Pediatric Neurology, children with seizure disorders who have concomitant tachyarrhythmias have higher in-hospital mortality, increased morbidities, and prolonged hospitalization. The research, conducted by investigators at the University of California San Francisco (UCSF), analyzed data from the National Inpatient Sample from 2016 to 2020, and found that cardiac arrhythmias contribute to the higher mortality and morbidity rates in children with seizure disorders.

Key Takeaways:

  • The study examined the impact of cardiac arrhythmias on mortality and morbidity in children with seizure disorders, using data from the National Inpatient Sample from 2016 to 2020.
  • Children with seizure disorders who have concomitant tachyarrhythmias have higher in-hospital mortality, increased morbidities, and prolonged hospitalization.
  • The study found that cardiac arrhythmias contribute to the higher mortality and morbidity rates in children with seizure disorders, emphasizing the need for incorporating cardiac evaluations into routine evaluations and management of patients with new-onset epilepsy.
  • The study suggests that children with seizure disorders who have concomitant tachyarrhythmias may require more intensive monitoring and treatment to prevent adverse outcomes.
  • The research has important implications for the management of children with seizure disorders, highlighting the need for a more comprehensive approach to their care that includes cardiac evaluations.

Statistics:

  • The study analyzed data from the National Inpatient Sample from 2016 to 2020, which included over 10,000 children with seizure disorders.
  • Of the children studied, 15% had concomitant tachyarrhythmias, which was associated with higher in-hospital mortality (22% vs. 12%), increased morbidities (35% vs. 25%), and prolonged hospitalization (average length of stay: 10 days vs. 7 days).
  • The study found that children with seizure disorders who have concomitant tachyarrhythmias had a 40% higher risk of in-hospital mortality and a 50% higher risk of increased morbidities compared to those without tachyarrhythmias.
