An electrocardiogram (also called an EKG) records the electrical signals in your heart. It’s a common and painless test used to quickly detect heart problems and monitor your heart’s health. This is a non-invasive way to help diagnose many common heart problems, including arrhythmias (abnormal heart rhythm), coronary artery disease (blocked or narrowed arteries in your heart), and heart attacks. An EKG can also tell us if your heart disease treatments, such as a pacemaker, are effective.
We might order an EKG if you have any of these symptoms:
- Chest pain
- Dizziness, lightheadedness or confusion
- Heart palpitations
- Rapid pulse
- Shortness of breath
- Weakness, fatigue or a decline in ability to exercise
