Atrial antitachycardia pacing and atrial remodeling: A substudy of the international, randomized MINERVA trial

Our data suggest that atrial electrical remodeling becomes important after about 12 hours of continuous arrhythmia. Compared to DDDR or MVP, DDDRP+MVP reduces ERAF and favors LAD reduction, suggesting that atrial antitachycardia pacing may reverse electrical and mechanical remodeling.
