In contrast to the well-documented changes in heart rate and respiration, post-seizure changes in blood pressure have received insufficient attention. Fluctuations in blood pressure may worsen brain injury and elevate the risk of Sudden Unexpected Death in Epilepsy (SUDEP), yet evidence regarding postictal blood pressure changes remains limited.
This multicenter study aims to investigate the changes of blood pressure and heart rate during post-epileptic seizure stage in epilepsy patients, providing high-quality evidence on postictal hemodynamic changes and laying the foundation for future interventions. The study will enroll 1100 seizure events from hospitalized epilepsy patients aged 14-80 years between October 2024 and March 2026. Data on blood pressure, heart rate and blood oxygen will be collected during multiple time intervals post-seizure, alongside clinical information such as seizure type, duration, and medication use.
