thedollhouselady,I'm sorry you've had to go through so much. you sound like a smart and strong person. I didn't know what heart trouble was until I was seventy four (currently) but i'm telling you the doctors really put us through it don't they. I just had a pacemaker put in due to heart block but it was like one doctor after another, me talking to their backs while they did charting, none of them seeming to remember who I was and then test after test. I finally said no more wasted time and energy for me. I cancelled my appointments and started a plant based diet. I felt better immediately. will probably have to see my pm doctor someday but i'm not ready for him yet. I wish you the best of everything!
