What is an Electrocardiogram (EKG) and why should I have one?
A. An EKG is a safe, non-invasive health screening used for diagnosing heart attacks and heartbeat rhythm abnormalities. You should have an EKG every one-to-three-years after age 40 if you have heart disease, or if you are at risk for developing heart disease because you have high blood pressure, high cholesterol or diabetes.
