Electrocardiogram (ECG or EKG) to assess the heart rate and rhythm. This test can often detect heart disease, heart attack, an enlarged heart, or abnormal heart rhythms that may cause heart failure.

Is ECG enough to detect heart problems?

Electrocardiograms, which monitor the heart's electrical patterns, don't reliably reveal the risk of having a heart attack. Unless you have symptoms of a heart problem, taking a cautionary look under the hood is unlikely to help—and could even be harmful.

Can you still have heart problems if your ECG is normal?

An abnormal reading does not necessarily mean that there is something wrong with the heart. On the other hand, some people may have a normal ECG recording even though they do have a heart disease. This is why you may need to have one or more other tests as well as the ECG.
