Hi @rmhc123
I have Apical Hypertrophic Cardiomyopathy (non obstructive) and during the past year persistent Afib w rvr presented itself up until the afib my only symptom was occasional lightheadedness. The afib caused fatigue and frequent very high heart rates even with rate medication. Afib needs to be treated aggressively when you have hcm. I see a cardiologist at Mayo clinic in Rochester. At my first visit he mentioned several medications he uses if I were to develop symptoms. When afib came he sent me to the heart rhythm clinic at Mayo. The Ep I saw gave me all my options and when I asked his recommendation he said he would start with medication so that is what I did. I had to be in the hospital three days to get this drug but now feel great and have been in sinus rhythm with no side effects for 9 months now. I also have an Apical aneurysm which happens in a small percentage of non obstructive patients. If you have afib, are you being treated for it? I can't say enough good things about Mayo Clinic. You might also check out the Hypertrophic Cardiomyopathy Association online and on Facebook.
