Biventricular pacemaker and defibrillator implantation in patients with chronic heart failure in China.

In China, among CHF patients with indications for primary prevention of SCD who received device implantation, non-ischaemic CHF was the main aetiology, and the most important cause of death was heart failure. No differences in all-cause death were observed between the CRT-D and CRT-P groups, but the CRT-D group had a lower SCD rate than the CRT-P group.
