VDDR may improve cardiac output versus VVIR in complete AV block; hypothesis-generating and leaves open confirmation in randomized trials.
Does a single pass VDDR pacing system improve cardiac output compared to VVIR pacing in patients with complete AV block?
A single pass VDDR pacing system provides stable P wave sensing and improves cardiac output compared to VVIR pacing in patients with complete AV block without adding implantation complexity.
