ATTENTION! Survive a heart attack doing only this!
Everybody could survive a heart attack, until the arrival of the ambulance, with doing only this simple thing. A person, which heart is beating incorrectly and starts feeling very bad, has only 10 seconds before losing conscience.
However, these persons could help themselves with coughing energetically and repeatedly.
You should take a deep breath before every caught, but the caught should be deep and extended, like producing a phlegm deeply from the chest. The breath and the caught should be repeated every 2 seconds without breaks, until the arrival of ambulance, or until the heart starts beating normally. This way, the victims of heart attack, could survive and make it up to the hospital.
