On their own, EKG tests have modest accuracy for detecting heart problems. As such, they are usually most effective when used in conjunction with other tests, such as various blood tests or a computerized tomography (CT) scan of the heart. There are also certain factors that can affect or interfere with the results of an EKG, such as various medications, exercise or smoking before the test, movement during the test, or fluid buildup in the abdomen. With that in mind, your doctor will likely provide you with some pre-testing instructions to ensure the most accurate results from an EKG test.
