In this issue of the Journal, ten papers related to the rescues of in-hospital ventricular fibrillation, and the mechanisms, drug-therapy, radiofrequency ablation, implantable cardioverter defibrillator (ICD) of ventricular tachycardia and fibrillaton were published. Although there were some short-come in those papers, new ideas or information were provided, such as the radial artery approach for catheter ablation of idiopathic left ventricular tachycardia, the feasibility, safety and efficacy of radiofrequency ablation of the delayed ventricular high frequency potentials during sinus rhythm to prevent the recurrence of ventricular tachyarrhythmia in patients with no-inducible or unstable tachyarnythmia, as well as the current states of primary prevention of sudden death with ICD in the mainland of China. In the next decade, continuous progress most likely will be made in the following aspects. Combination of modern cardiac images such as multidetector CT with the electrophysiological techniques will provide more precise anatomic landmarks about the sources of arrhythmia. New electrode material, new forms of energy transformation and pulsed far-field low-energy defibrillation will reduce the complication rate of ICD, prolong the longevity of ICD, and make the ICD therapy less painful. Advances in remote magnetic navigation, robotic control and internet techniques will make the remote intervention of arrhythmia possible. We need catch up the progress of modern technology and publish more papers with emphasis on innovation in Chinese journal.
