Frequent question: Does an ECG show all heart problems?

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.

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

How reliable is ECG in detecting heart problems?

The ECG is by far not as accurate as many patients and doctors would like to believe. Often, the findings of a measurement are completely normal even though a heart attack has taken place. As a result, ECG does not detect two out of every three heart attacks at all or not until it is almost too late.
