If you have a normal blood pressure and heart rate put pain in left arm and gas can you be having a heart attack?

Yes: If you think you're having a heart attack, going online & waiting for an answer is wrong thing to do. You only have 6 hours to prevent irreversible damage. Call 911 or local emergency services immediately. Don't drive yourself b/c you don't want to risk passing out. While waiting, take regular aspirin.
