Qinming8631D/DR is a programmable dual-chamber implantable cardiac pacemaker, which is used to treat bradycardia. Compared with single-chamber pacemakers, dual-chamber pacemakers are suitable for patients who need to increase cardiac output. These patients include patients who have or may become pacemaker syndrome.
Chinese first dual-chamber pacemaker series with independent intellectual property.
Patent technology of RF power supply provides safe program control without consuming the battery power.
New generation programmer provides accurate control of the parameters.
Imported lithium-iodine battery ensures a durable lifetime.
Optimized ergonomic design makes it comfortable after implantation.
Multiple protections effectively avoid interference to guarantee the patient's safety.
