Hi , I first had pulmonary embolism 8-25-14 that resulted in cardiac arrest x2 was told vfib, almost one year later woke up and had massive heart attack with resecutation was required again, all test including cath and stress have been great, no blockage, well over the last couple mths I've developed chest pain that doesn't last long , a few seconds to sometimes a couple minutes at most, but with all the same signs as attack, the arm pain , sweating all of it , and it seems to reach a spike in pain, I break out in sweat and boom its gone , this is sometimes as much as 5-10 day, when first started I called ambulance and hospital said I was OK it wasn't heart, but what else could it be
