RESUMO
Factors influencing the temperature-sensing accuracy of an ablation catheter are analyzed, in this paper, from the two aspects of the thermocouple temperature sensor, which are the TC length and the TC hole's diameter of the ablation electrode. Meanwhile, differences between products from different companies are given too.
