Cardiac resynchronization therapy (CRT) with or without defibrillators (CRT/CRT-D), as well as the implantable cardioverter defibrillator (ICD) device, has been widely used both to improve the prognosis of heart failure and to prevent sudden cardiac death. With the increased training and education of electrophysiologists in China, CRT and treatment by ICD have become standardized and many patients have benefited from the procedures. However, the current challenges in applying CRT and ICD treatment within China include the underuse of device therapy, technologic gaps between Western countries and China, and regional differences in the use of CRT/ICD. Understanding the current national status of device therapy may help promote scientific, technological, and clinical improvements in therapies against heart failures occurring within China.
