How does one stop chest pain during a heart attack?

CP: CP at random times- does not sound too ominous. It has to be evaluated keeping in view of cardiac risk factors. Get checked atleast once.

See below: Most importantly, call 911 to make sure that you will be treated properly in a hospital setting. While you are waiting, two things may help - a sublingual nitroglycerin, or taking a deep breath and holding it, that redistributes blood flow to the coronaries.

Variety of things: Nitoglycerine, morphine, oxygen for starters as well as beta blockers for high hr or htn.
