I see a duplicate post by you which has some additional information, namely:
"Hello. I've recently had a pfo closure ( two actually ). One in March ( 2010 ) and another in June. Immediately after the latest one I started having issues with my heart rhythm which would make my heart rate go up. "
I bring that information to this thread and will delete the duplicate. I add the dates you give adds credibility to the thinking that you need to give your heart more time to heal.
I'm sure you're looking for someone with "pfo closure" experience, I am not such a person. So, I ask, what is "pfo closure" (I'd guess closure of a hole between heart chambers)?
Whatever, healing of surgery in the heart takes time, have you given the healing process sufficient time? Said another way, I believe it can "resolve" itself if you are still in the healing stage.
