Hypothesis-generating for accelerated pacing in HFpEF; randomized trials needed before any practice change.
Does accelerated atrial pacing reduce left-heart filling pressure in patients undergoing AF catheter ablation and in HFpEF computer simulations?
Accelerated atrial pacing acutely reduces left-heart filling pressure, suggesting it may be a potential therapeutic strategy to alleviate congestion symptoms in HFpEF.
Loon et al. (2024) studied this question.
