Background:It has been recently emphasized that the use of slow sensors to monitor the luminal esophageal temperature (LET) during atrial ablation can be seriously dangerous to the patient.

Objective:We want to investigate such a feature in a quantitative way in order to understand how fast a thermal probe should be in order to be reliable.

Methods:We formulate a model allowing reconstructing the real temperature evolution from the one recorded, knowing the sensor response time.

Results: We compare measured and real temperatures and we perform a virtual comparison among sensors with different response time starting from actual clinical data.

Conclusions:Sensors with a response time of 4 or more seconds are not safe in the presence of rapid esophageal temperature variations, i.e. when thermal monitoring is actually needed.
