A novel algorithm increases the delivery of effective cardiac resynchronization therapy during atrial fibrillation: The CRTee randomized crossover trial

In a cohort of CRT patients with a history of AF, eCRTAF significantly increased %eCRT pacing and %Vp during AF with a small increase in mean HR. This algorithm may represent a novel noninvasive method of significantly increasing effective CRT delivery during AF, potentially improving CRT response.
