Why the study?
Does rate responsive pacing mode (VVIR) improve exercise duration compared to fixed-rate demand mode (VVI) in patients with coronary artery disease and angina pectoris?
Does rate responsive pacing mode (VVIR) improve exercise duration compared to fixed-rate demand mode (VVI) in patients with coronary artery disease and angina pectoris?
In patients with CAD and angina, rate responsive pacing (VVIR) improves exercise capacity and heart rate response without worsening angina symptoms compared to fixed-rate pacing.
No takes yet. Share an insight, caveat, or question.
VVIR pacing improves exercise capacity in CAD patients with angina; supports rate-responsive modes over fixed-rate VVI in practice.
Cock et al. (1989) studied this question.
