Rationale and Objectives. We sought to induce large zones of coagulation necrosis using radiofrequency (RF) with perfusion electrodes and to define optimal parameters for this system. Methods. We developed RF electrodes with internal cannulas to enab

We determined whether heat distribution along a radiofrequency (RF) electrode would be uniform when longer tip exposures are used and whether local temperature effects would influence the shape of induced tissue coagulation.Thermistors were embedded

Rationale and Objectives. We evaluated the parameters affecting the size and distribution of thermal tissue damage produced by radiofrequency electrodes. Methods. Thermal lesions were produced by electrodes connected to a radiofrequency generator in

Successful lesion formation using radiofrequency energy requires adequate tissue heating. Temperature monitoring during ablation may thus improve the efficiency of radiofrequency catheter ablation. Each of five anesthetized, closed-chest adult mongre

The method of radiofrequency heat lesion generation is reviewed with specific reference to the dorsal root entry zone. Experimental data on the impedance of electrolytic media as a function of temperature are reported, and their relation to what shou
