¿Es ventajoso adaptar el controlador PI al tipo de electrodo en ablación cardíaca percutánea por RF?: Estudio basado en modelos teóricos

Abstract

The commercially available generators for radio- frequency (RF) cardiac catheter ablation employ a proportional-integral (PI) controller. Its performance is based on the value of two parameters, Kp and K i, 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. © 2013 Springer.
