Also planning to start soon and am on a beta blocker. I also have had paroxysmal atrial fibrillation so am somewhat nervous. I have hypertrophic cardiomyopathy and an implantable defibrillator also. My numbers aren't so bad but I have had 4 fractures in 5 years, most recently my humerus which was a horrible displaced spiral fracture necessitating surgery.

I hope Tymlos helps and doesn't cause me more problems.

Have you started it yet?
