If you’re asking whether that claim is true: there is no 10-second maneuver you can do yourself that reliably stops or reverses a heart attack.
If you think you’re having a heart attack right now:
-
Call your local emergency medical service immediately. Don’t drive yourself.
-
Sit or lie down, stay as still and calm as possible, and unlock the door if you’re alone.
-
If you have prescribed nitroglycerin, take it exactly as directed.
-
Do not rely on coughing, forceful breathing, drinking water, or other viral “10-second” tricks.
-
If you become unconscious and aren’t breathing normally, someone nearby should start CPR and use an AED if available.
Common warning signs include chest pressure/pain, pain spreading to the arm, back, neck or jaw, shortness of breath, sweating, nausea, or sudden weakness.
