Just because a pacemaker is working exactly as it's supposed to, it doesn't mean it's meeting your needs.  You mention "doctor". If your doctor is not an electrophysiologist, find one now.  You need someone who specializes in the heart's electrical system.

You say "still" but did you have these symptoms before your PM?  If so, the CRT isn't likely to change things overnight but you shouldn't have these problems with an LVEF of 45%, either.  There is something else going on.  These are classical symptoms of low blood oxygen.  Besides the somewhat low LVEF (not all that bad, really) do you have anything else going on?  Arrhythmias (Afib, Aflutter, long strings of PACs or PVCs)?  Have they ruled out structural problems (blockages, etc)?

Are you on any medication? I have a CRT pacemaker fitted due to a dual lead pacemaker causing LVSD. I am on a beta blocker and ace inhibitor. These caused me dizziness at first.What is your blood pressure? Mine is sometimes low due to the medication.

Publications suggest that 30% of CRT patients are "non-responders." Physiological resynchronization therapy to the rescue. Just one lead with the electrode at the His bundle (Google that) seems to provide a better outcome according to clinical study reports. Check out www.His-pacing.org. Learn about natural, physiological ventricular activation and contraction by pacing the His/Purkinje system, "His bundle pacinf is the only pacing methods capable of providing physiological pacing." I think or CRT as a crude surrogate of physiological pacing,
