Information on biventricular pacemaker and meds

I had a biventricular pacemaker implanted on aug. 27/2010 at the Cleveland Clinic. They were very competent. This pacemaker replaced  a 2 wire, right heart only, pacemaker, which I had for 2.25 years,  My ejection fraction was 35% with the old pacemaker. Now with the new biventricular pacemaker it is in the normal range. I do not feel any better now, I understand that it can take from 6 to 12 months for the new pacemaker to reverse remodel the heart. It appears, from a recent echocardiogram that my heart is now fine on systolic, but on diastolic it is not relaxing and filling properly.  I now need to determine the best meds, that will help the new pacemaker with the reverse remodeling, I would appreciate a respnse from someone who has information on this subject.
