- Permanent pace-maker implantationPermanent pace-maker implantation involves placement of a single wire or lead (Single Chamber PPI) into the Right ventricular chamber of the heart (VVI; VVIR) or two wires or leads (Dual Chamber PPI), one each into the Right ventricle and the Right atrial chamber of the heart (DDD; DDDR).www.miotinternational.com/centers-of-excellence/miot-institute-of-cardiac-care/i…
What Is DDDR Pacing? Pacemaker - MedicineNet
Dual-chamber rate-modulated (DDDR) pacing is a mode that is programmed into a pacemaker and recommended for patients with atrioventricular block and sinus node dysfunction.
