Steps

  1. Learn the signs: chest pain, pressure or squeezing, and also breathlessness, nausea, back, jaw, neck or arm pain, cold sweat, lightheadedness and sudden fatigue.
  2. If symptoms start, stop what you are doing and call your local emergency number, 911 in the US.
  3. Say: I think I may be having a heart attack, and give your exact location.
  4. Unlock the door and sit somewhere you can be reached.
  5. Do not drive yourself or wait to see if it passes.
  6. If someone near you collapses and is not breathing normally, start hands-only CPR and send someone for a defibrillator.
  7. Take a certified CPR class so you can act for someone else.
