What should be done if the pain starts suddenly in the chest?

If you suddenly start having a sharp pain, then know what steps should be taken immediately.
Since most people are alone when the heart visits, they are suffering without any help in breathing, they seem to be senseless and possibly they have only 10 seconds.

In such a condition, the person should be taught loud because he can keep himself common by doing so.
In this situation, it should be repeated with a loud breath and every cough is so fast that the chest comes out.
Until you help, continue this process for every two seconds, so that the heartbeat becomes common.
Strong breathing causes oxygen in the lungs, and the heart makes it dry because of the cough that runs regularly.
