Cardiac arrhythmia is regarded as one of the three major cardiovascular diseases. For treatment, non-pharmacologic therapy such as antiarrhythmic device implantation and catheter ablation is frequently used. In this article, recent advancement in the management of the cardiac arrhythmia including pacemaker therapy for bradycardia, drug therapy and catheter ablation of atrial fibrillation, implantable cardioverter-defibrillator therapy for ventricular arrhythmia and sudden cardiac death, and cardiac resynchronization therapy for drug refractory heart failure with ventricular dyssynchrony will be reviewed. I hope this review can be of help for the health care providers in clinical fields.
