Cardiac radiofrequency ablation is an interventional procedure that is used clinically for the treatment of arrhythmias, with sequelae of unsuccessful treatment or procedural complications. If the exact target of the arrhythmia is not found and the treatment is not successful, the arrhythmia may be re-induced or reoccur after the cardiac ablation procedure. It may also cause sequelae, such as cardiac perforation leading to cardiac compression, respiratory distress, purple lips, and increased heart rate. If the atrioventricular block is caused by the conduction bundle injury associated with the accidental injury during surgery, and symptoms such as dizziness, weakness, chest pain, or even sudden fainting occur, and in severe cases, pacemaker treatment is required. At present, this technology has a history of more than 20 years, and although there may be associated sequelae, the success rate is also very high with little trauma.
