Abstract:Magnetic navigation system (MNS) is the only tool for cardiac interventional diagnosis and treatment based on magnetic navigation now in the world.The methodology of interventional therapy in cardiovascular diseases has been completely changed by MNS, which has been widely applied in interventional treatments of arrhythmias and coronary heart disease in abroad and yet seldom used in China.The paper will make a review mainly on radiofrequency catheter ablation of arrhythmia guided by MNS on the setting of composition, working mechanisms and procedures. Arrhythmias are including supraventricular arrhythmia, ventricular arrhythmia and ones due to congenital heart disease.
