There are single-chamber and dual-chamber pacemakers, domestic and imported. Single-chamber pacemakers are generally cheaper, with domestic ones costing around RMB 18,000, imported ones around RMB 30,000, and dual-chamber ones around RMB 40,000 to 50,000. The general cost of inpatient pacemaker placement is around 30,000 to 50,000 RMB, but of course, different regions and different levels of hospitals charge different rates, and there will be some differences. (Pacemakers) generally need to be replaced every 7-8 years. The two best pacemaker brands in the world are Medtronic and St. Jude.
