Is there any harm to the body of taking electrocardiography?

What information does electrocardiography provide?
A simple electrocardiographic examination can provide a wide variety of information about your heart. However, not all information is permanent in electrocardiography. This is why electrocardiography may be normal, even though there is a serious underlying heart problem. For example, while there are some abnormalities in electrocardiography taken during chest pain or palpitations, the abnormalities may disappear completely after the chest pain or palpitations have passed. Therefore, electrocardiography taken at the time of complaint is valuable and may sometimes need to be repeated at frequent intervals. However, electrocardiographic evidence of a previous heart attack or thickening of the heart muscle is not easily lost. Therefore, keeping your old electrocardiograms is sometimes useful in comparison to evaluate new abnormalities.
