That is quite a story you shared @camtak! I'm so glad you found Mayo Connect too, welcome aboard.
How wonderful that you are a super athlete. But no wonder you were so shocked. I was too when I found out I had HOCM at 62. Your story is so similar to mine. I was told no more yoga or weight lifting too, because some of the strong poses, and the strain of lifting something heavy could send you into V-tach. And V-tach kills you! And isn't the eating a large meal deal the weirdest thing? Who would think?!
What a blessing to be have been sent to the Mayo in Arizona. You mention you were sent to Mayo, I assume you mean Rochester? That is where the finest in the world are for HCM and HOCM. Will you need to go back to see them for follow up?
