Monitoring esophageal temperature during catheter ablation.

I comment on a paper just appeared on JAFIB, aimed at providing an index quantifying the convenience of monitoring esophageal temperature during catheter ablation. The authors base their calculation on the data from four papers. I point out that the data from the two papers strongly against monitoring should be interpreted differently and I suggest how to retrieve more data for a more reliable determination of the said index. In addition, I briefly discuss the so-called antenna effect, sometimes put forward to discourage temperature monitoring.
