Resumen
The commercially available generators for radiofrequency (RF) cardiac catheter ablation employ a proportional-integral (PI) controller. Its performance is based on the value of two parameters, Kp and Ki, which are fixed, regardless the electrode type, i.e. different diameter, length, and temperature sensor type. Our aim was to assess by means of theoretical models whether values of Kp and Ki specifically chosen for each electrode type could affect the performance of the temperature-controlled RF cardiac ablation. We used theoretical models solved by the Finite Element Method. The results suggest that the specific choice of Kp and Ki parameters adapted to different types of electrode does not provide a clinically important enhancement
