What is it like to do radiofrequency ablation?

Catheterradiofrequency ablation (RF) is an interventional technique used to block abnormal conduction tracts and origin of tachycardia by radiofrequency ablation, which releases radiofrequency current through veins or arteries into specific parts of the heart cavity to cause coagulated necrosis of local endocardial and subendocardial myocardium.

First, the skin where the catheter is inserted (groin, arm, shoulder or neck) is disinfected, and local anesthetic is used for local anesthesia. Then the venous/arterial vessels were punctured with a puncture needle, and the catheter was inserted into the heart cavity through the vessels for electrophysiological examination. A long flexible catheter that carries electrical signals into and out of the heart. The electrode catheter records the electrical activity of different parts of the heart, and delivers weak electrical stimulation to stimulate the heart, in order to induce arrhythmia, clear diagnosis of tachycardia; The doctor then uses a catheter to locate the exact location of the abnormal electrical activity in the heart (a process called mapping) and sends radiofrequency current through an ablator to treat the tachycardia.

The patient is usually awake during the whole process, and sometimes the doctor will use sedatives to relieve the patient's tension, and the patient will be monitored throughout the whole process. Electrophysiological tests generally do not cause pain, and patients will not feel the catheter as it travels through the blood vessels and heart chambers; During the examination, the doctor may use a weak current to stimulate the heart, and the patient will not feel these electrical pulses, which will often induce tachycardia. The feeling is the same as in the previous attack (there may be dizziness, dizziness, palpitations, chest pain or shortness of breath, etc.), and the doctor can be informed; These operations carry little risk and are relatively safe. After radiofrequency ablation, the patient should rest in bed according to the doctor's advice, with sandbag compression for 6 hours at the venipentesis site and 8-12 hours at the arterial puncture site, and brake the affected limb (restrict immobility), and pay attention to whether bleeding.
