Definitely. An electrocardiogram (EKG or ECG) is a recording of the heart's electrical activity as a graph or series of wave lines on a moving strip of paper. This gives the physician important information about the heart. For example, it can show the heart's rate and rhythm. It can also detect decreased blood flow , enlargement of the heart or the presence of either current or past heart attacks.
Depending on what the results show, in combination with the patient's medical history and a physical exam, the physician may order further tests or a combination of medications and lifestyle changes.
I have peformed thousands of EKG's when I use to work in the ER and they always showed past heart attacks, some were days before, weeks before, months before, or even years before.
