Why the study?
Does AAIR pacing compared to DDDR pacing improve ventricular function during exercise in patients with sinus node disease and intact AV conduction?
Does AAIR pacing compared to DDDR pacing improve ventricular function during exercise in patients with sinus node disease and intact AV conduction?
In patients with sinus node disease and intact AV conduction, AAIR and DDDR pacing are equally effective at increasing cardiac output and LV filling during exercise.
No takes yet. Share an insight, caveat, or question.
AAIR and DDDR pacing are equivalent for exercise cardiac output in sinus node disease with intact AV conduction; confirms no mode superiority for hemodynamic response.
Gallik et al. (1994) studied this question.
