... April 22nd of 2014 because of my heart fibrillation condition i have been experiencing since 2009. I am 50 years old and i just experience my second shock already. I just notice that as months go by i am slowly loosing my stamina compared to how i was before. i am constantly out of breath and my pacing experience gets to be more frequently than ever. I wonder if anyone out there has the same experience i have or is there ever a solution to this deteriorating body of mind. so desperately seeking any answers from anyone. thanks
