How do you survive a heart attack when you are alone?

You may suddenly have severe pain in your chest extending to your arm and jaw, and you may be alone and far from the hospital, so how do you survive a heart attack?
Since many are alone when they have a heart attack, a person whose heart beats irregularly and begins to feel dizzy, has only XNUMX seconds before losing consciousness.
And these can help themselves by coughing or (coughing) strong and frequent.

It is important to take a deep breath so that it precedes the cough, and the cough should be deep and long.
This process must be repeated about every two seconds continuously until help arrives or the heart feels normal again.
A deep breath delivers oxygen to the lungs, and coughing compresses the heart and keeps the blood circulating. The pressure on the heart helps to restore the rhythm of the heart.
