The patient with atrial fibrillation and heart failure poses a challenge in optimizing the benefits of cardiac<unk><unk>  (CRT).  The rapid ventricular response (RVR) associated with atrial fibrillation can minimize the benefits of CRT, and pharmacologic rate control or AV ablation may optimize the benefit of CRT.
