Description
Summary:The purpose of this study was to evaluate the differences in transient thermal response (TTR) among various types of commercial esophageal temperature probes (ETPs) in the United States in an experimental model. There is little information regarding the variation in TTR among various commercial ETPs that are approved for atrial fibrillation ablation. We compared various thermodynamic characteristics including, mean thermal time constant (τ), time to rise 1°C (T1°C), time to peak temperature (Tpeak), and decay time among 22 different ETPs. Each probe was submerged in a constant-temperature water bath maintained at 37 ± 0.5°C and then quickly (
