When people suffer a heart attack usually are almost helpless. The person whose heart starts to beat improperly and begins to feel faint, has only about 10 seconds before losing consciousness.
In order to help yourselves start energetically and continuously coughing. Take a deep breath before each cough. The coughing must be deep and prolonged, as when coughing up sputum from the lungs.
Inhaling and coughing must be repeated every two seconds until help arrives, or until you feel that your heart beats in a regular rhythm. Deep breaths let oxygen into the lungs and the movements made during the coughing pressure the heart and keep the blood circulation.
The pressure on the heart helps restore a normal rhythm. In this way, heart attack victims can get to a hospital.
