Cerebral Oxygenation and Awareness During VT Ablation

Completed

• Conditions: Cerebral Oxygenation
• Interventions: Procedure: NIRS during ventricular tachycardia ablation

• Registration Number: NCT05097170
• Lead Sponsor: Hacettepe University

Brief Summary

It is aimed to examine the effect of the decrease in blood pressure that occurs during the ventricular tachycardia ablation process on cerebral oxygenation and awareness.

Patient's age, cardiac measurements (ejection fraction-EF), basal vital values, procedure time (especially activation and pacing mapping), and localization of the arrhythmia, may affect the NIRS and BIS response to blood pressure drop. In addition to the effects of patients' demographic information, cardiac capacity and procedure time on NIRS and BIS values (downtrend and duration), correlations of these values with other monitoring parameters (ETCO2 and SpO2) intended to be displayed.
