The radiofrequency ablation procedure is to send the device into the heart cavity from the lower extremity blood vessels, and after determining the site of application, the local tissues are made coagulably necrotic by electric current to achieve the eradication of tachyarrhythmia, which is currently a very mature technology and will not cause harm to the human body. Premature heart beats are not necessarily treated with radiofrequency ablation, but can be used for tachyarrhythmias, atrial fibrillation or ventricular premature beats, which are not necessary in the case of atrial premature beats. After local disinfection, followed by anesthesia, the procedure can be performed by puncture. The ablation site is selected and radiofrequency current is sent through the instrument, and the ablation process is always awake, with a success rate of more than 90%.
