Dependence of destruction from the characteristics of radiofrequency impact and length of the electrode

The work is devoted to research of catheter radiofrequency ablation modes (CRFA) in the treatment of the heart pathways disease. Lesions sizes of myocardial tissue during CRFA have been obtained in the experiment depending on output of the generator power, the electrode temperature, the size of electrode tip, duration of RF exposure. The work gives suggestions for optimal catheter radiofrequency ablation modes.
