Clinical Trial 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.

Related Conditions & MeSH terms

• Cerebral Oxygenation
• Tachycardia
• Tachycardia, Ventricular

Intervention

Procedure:
• NIRS during ventricular tachycardia ablation
NIRS: Near-infrared spectroscopy is a measurement technique that non-invasively and continuously monitors the balance between cerebral oxygen consumption and delivery. BIS: BIS is an electroencephalogram-derived parameter developed to monitor the hypnotic effects of anesthesia.
