Last night after dinner I was extremely tired and then all of the sudden I became lightheaded and felt I was going to faint. My heart was beating so fast I felt like it was about to fall out of my chest. This all lasted for about 15 min. I was close to dialing 911 but didn t. Instead I put a cold cloth on my neck and took deep breaths which seemed to help but I was terrified! My dad has had heart attacks and now has a pace maker and heart problems do run on my dad s side of the family. I m 35 years old -female. Do you think it was just a panic attack? I ve never experienced anything like this before. Should I make an apt for a physical? Or what type of doc. should I go see? Today my chest seems a little sore.
