If this is about a suspected heart attack, there is no 10-second trick that reliably saves your life. The safest response is to act immediately:
Call your local emergency number now if you have chest pressure/pain, shortness of breath, sweating, nausea, or pain spreading to the arm, back, neck, or jaw.
Sit or lie somewhere safe and stop exerting yourself. Unlock the door if you’re alone.
Chew an aspirin (160–325 mg) only if emergency medical guidance recommends it and you are not allergic to aspirin, have been told to avoid it, or have active significant bleeding.
Do not drive yourself to the hospital.
If you become unresponsive and aren’t breathing normally, someone nearby should start CPR and use an AED if available.
If you’re asking because you or someone with you is having these symptoms right now, call emergency services immediately rather than continuing to read.
