RF energy is not the higher the better, should choose the right energy. At present, the commonly used radiofrequency energy is low-voltage high-frequency (30kHz~1.5SMHz) electrical energy.
The mechanism of catheter radiofrequency ablation (RFCA) is that the radiofrequency current is released by the electrode at the head end of the catheter, and then converted into heat energy between the endocardium and the head end of the catheter in the local myocardium, which makes the specific myocardial tissue cells degenerate and necrolyze, and then the myocardial autonomy and conduction can be changed in this part of the myocardium and the treatment of cardiac arrhythmia.
Radiofrequency energy is currently used as a low-voltage, high-frequency (30kHz~1.5SMHz) electrical energy, which can be converted into local thermal energy at 46~90 degrees Celsius and does not require general anesthesia during the operation.
Currently, RFCA is an important therapeutic method for the treatment of tachyarrhythmias (e.g., atrioventricular nodal tachycardia, atrioventricular tachycardia, and paroxysmal atrial fibrillation, etc.).
Specific energy selection should be based on the lesion, not the higher the better.
