Why the study?
Does the site of pacing (right, left, or biatrial) modulate atrial repolarization and dispersion in isolated rabbit hearts?
Does the site of pacing (right, left, or biatrial) modulate atrial repolarization and dispersion in isolated rabbit hearts?
In isolated rabbit hearts, left atrial pacing minimizes dispersion of atrial repolarization compared to right atrial pacing, with no additional benefit from biatrial pacing.
No takes yet. Share an insight, caveat, or question.
Left atrial pacing effects on repolarization remain experimental; leaves open translation to human AF prevention.
Wood et al. (1996) studied this question.
