How do I know if I am having a heart attack?

Individuals suffering a heart attack experience heart pain in different ways. Most
commonly there is an onset of pain in the middle of the chest which is unrelieved by such
measures as taking antacids or resting, or by placing a nitroglycerin tablet under the
tongue. Most patients experiencing damage to the heart muscle, which is the source of
heart attack pain, describe this event as a feeling of a heavy weight on their chest which
may radiate to the arm, back, or up the neck.
In addition, sweating is often a strong component of the heart attack syndrome in the
early moments of the event. Furthermore, patients sometimes feel nauseated, experience
weakness, shortness of breath and may express feeling a sense of "impending
doom". However, the actuality of a heart attack presenting with all of these
components occurs only about half of the time, and oftentimes patients do not experience
any of these classic symptoms.
Consequently, if you should experience unexplainable pain of this type which is not
relieved by simple measures, medical help should be sought immediately to clarify the
source of the problem. It is important not to experiment with or rely on antacids,
exercising, or other maneuvers which may mislead or convince you that you are not having a
heart attack. Furthermore, if you have previously been told that you have any problems of
narrowing of the vessels or arteries supplying blood to the heart, or have previously
experienced the symptoms of a heart attack, this pain should be taken very seriously and,
again, medical attention should be sought immediately. Pain coming from the heart can also
signify an early disorder in the circulation of blood in the heart.
As mentioned above, in the event that you have available physician-prescribed
nitroglycerin tablets, one tablet should be placed under the tongue immediately. If the
pain does not go away within five minutes, another nitroglycerin tablet should be
administered under the tongue and an ambulance should be called. If the pain has still not
subsided in another five minutes, a third nitroglycerin tablet may be taken. However, do
not take a fourth nitroglycerin tablet. Seek medical attention immediately.
It is important to note that there are variances in heart pain and, when treated early,
the likelihood of preventing a future heart attack is great.
