How we can identified that a chest pain is an emergency?

Severity matters: Any chest pain that is severe and lasts more than just a few seconds at a time should be considered an emergency. Chest pressure may be cardiac. Pains that are not heart related include brief (1 second to a few seconds) pains that come and go, and pain aggravated by deep breathing. The latter pain, although not cardiac, could still be serious, as it could indicate a pulmonary (lung) embolism.

Chest pain in the ER: There are many causes of chest pain. Some are dire emergencies while others are from minor conditions. In an er we are mainly concerned with making sure you don't require emergency intervention. It can be frustrating for patients when all of our er tests are normal. However this is always good news! even if a final answer to your symptoms is not found in the er, for many it is place to start.
