hi, my story in brief , my husband had a food poisend before 2 month , and he vomiting a lot , that what they said In the hospital , and after that , he did lots of check up with a doctors to make sure that his heart is fine cause it was beating very fast after the vomiting , and when he check with the doctor they said there is a problem with the heart , so he did the x-ray and the stress test , they found that during the rest the heart is fine and the blood circulation excellent , but under the stress the the blood circulation little slow , and the doctor said there is little blocked in the lower area of the heart , and there is nothing to do with the vomiting , my question is how when he relax or not under pressure the heart is good and under the pressure is not , ? every body going through a lot of pressure , and of course the body will react different , am I right , ? and he said it might need a little operation to open this blockage , is that true? what if he decide not to do it cause he didn't feel a pain in the chest , and he is like gagging , and he is a soccer player, thanks .
