Shane, you are a brave man, stay strong. I had a similar experience a few years ago it's not a nice thing. i was hooked up like you and i thought i was going to die. the consultant said it was a stress attack and there was no damage to my heart but i needed to take it easy as i had been doing too much. anyway, mate, i hope you feel better soon and make a full recovery, just remember your family and friends love you and they will alway be there when you need them. thanks for sharing you experiance with us all.
