As a paramedic, I see chest pain calls on a daily basis. Some are the real deal and others are from causes other than the heart. However here are some common signs/symptoms:
Shortness of breath
Chest pain that cannot be isolated to one spot
Radiation of pain to the left arm, neck, jaw, or between the shoulder blades
Profuse sweating
Nausea, vomiting, or diarrhea
Chest pain can be described as someone standing on your chest, dull pressure, tightening of the chest, to name a few. Most of the true cardiac related chest pains will be pain that no matter what you do will not go away. It can start of as a nagging pain that escalates or it could start off with severe pain.
My advice to anyone with chest pain, call for help immediately. I would rather be called to your location while you are still breathing. There are too many people that think it will go away out of denial, by that time heart muscle is lost or worse, you have a cardiac arrest and the chances of bringing you back are slim to none.
Today’s paramedics are well trained and carry all the medications in our ambulance that are in the ER for cardiac situations. Remember, time is muscle. Once cardiac muscle is damaged, there is no reversal.
