The Effects of Sevoflurane and Desflurane on QT Interval Measured With Cardiac Electrophysiological Balance Index

A Prospective Randomized Comparison of the Effects of Sevoflurane and Desflurane Anesthesia on QT Interval Measured With Cardiac Electrophysiological Balance Index

The primary aim of this study is to compare the effects of sevoflurane and desflurane on the QT interval. The secondary aim of this study is to compare the effects of drugs used in the induction and maintenance of anesthesia on the QT interval by calculating the Bazzet formula and iCEB.
