Dual-chamber pacing improves QOL over VVIR; confirms physiologic modes as preferred in sinoatrial disease or AV block.
Does DDDR pacing improve quality of life compared to DDD or VVIR pacing in patients with sinoatrial disease or complete AV block?
DDDR and DDD pacing modes provide significantly better quality of life and fewer physical malaise symptoms compared to VVIR pacing in patients with sinoatrial disease or complete AV block.
