Hello. : Hello. Usually the pain of myocardial infarction is not so well circumscribed. However, you had tachycardia (rapid heart rate), chest pain, and diaphoresis (sweating) and you are not young. Didn't mention if your breathing was impacted. Although the actual event as it was occuring won't be captured on an ekg; i think it is still prudent to be evaluated. I do not know if you were having a cardiac arrythmia. Here are possible symptoms of a mycocardial infarction (heart attack). Chest pain, tightness, squeezing or fullness is the most common presentation. However the pain can also present in the upper back, the upper middle abdomen, jaw, head, teeth or in the arms (left more than right). One could have nausea, vomiting or it could feel like indigestion or heartburn. Feeling short of breath, sweating and just feeling out of sorts can also occur. About a fourth of people have no significant symptoms during a heart attack. Even though you are feeling fine now, i recommend that you advise your doctor of this event and that you be evaluated. Take care.
