The principle of radiofrequency therapy technology
The principle of radiofrequency ablation: The treatment mechanism is mainly thermal effect, which is commonly used for the treatment of tumors and atrial fibrillation. Using radiofrequency electrodes to puncture tumor tissue, an electromagnetic field is formed under the action of high-frequency alternating currents ranging from 375 kHz to 500 kHz, causing high-speed friction and collision between water and protein plasma within the tumor tissue, resulting in thermobiological effects and cell coagulation necrosis; The use of radiofrequency catheter to release radiofrequency current causes impedance heat to form in local myocardial tissue, and then destroys myocardial cells in the ablation area through heat conduction, thereby achieving the goal of treating atrial fibrillation.
