EP radiofrequency generators: Significant offsets between selected and delivered power?

abstract：INTRODUCTION:While some posteroseptal and left posterior accessory pathways (APs) can be ablated on the tricuspid annulus or within the coronary venous system, others require a left-sided approach. "Fragmented" or double potentials are frequently recorded in the coronary sinus (CS), with a smaller, blunt component from...
