Procedure of radiofrequency cardiac ablation

Electrophysiological examinations and radiofrequency ablation are performed in a specially equipped operating room (called the catheterization room). Cath lab staff typically include electrophysiologists, assistants, nurses, and technicians. When the patient lies on the X-ray examination bed, the medical staff will connect various monitoring devices to the patient's body, and cover your body with a sterile sheet. The medical staff will wear sterile operating clothes and gloves. 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.
