I was on Verapamil before a septal myectomy and have been on Metoprolol 50 mg SUCC ever since the surgery with no noticeable side effects. I realize those in the discussion have not had surgery, but I would like to suggest discussing calcium blockers vs beta blockers with your cardiologists. You may want to read https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/beta-blockers/art-20044522 and https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/calcium-channel-blockers/art-20047605 to get an informed background leading into a discussion with your cardiologist.
