question: H..Please, My husbands 37 and 1 1/2 hr ago he said to me that his chest hurt and his heart was beating weird. I'm a nursing student so I got my stethoscope and listen to his heart. I can hear his heart beat fast and then slow down. He says there are no symtoms of pain,short of breath or dizziness. Why now and should we be conceren. Sheree'
