ECG (Electrocardiogram)
ECG (Electrocardiogram)
An electrocardiogram records the electrical signals in the heart. It’s a common and painless test used to quickly detect heart problems and monitor the heart’s health.
An electrocardiogram — also called ECG or EKG — is often done in a health care provider’s office, a clinic or a hospital room. ECG machines are standard equipment in operating rooms and ambulances. Some personal devices, such as smartwatches, offer ECG monitoring. Ask your health care provider if this is an option for you.
Why it's done?
An electrocardiogram is a painless, non-invasive way to help diagnose many common heart problems. A health care provider might use an electrocardiogram to determine or detect:
- Irregular heart rhythms (arrhythmias)
- If blocked or narrowed arteries in the heart (coronary artery disease) are causing chest pain or a heart attack
- Whether you have had a previous heart attack
- How well certain heart disease treatments, such as a pacemaker, are working
You may need an ECG if you have any of the following signs and symptoms:
- Chest pain
- Dizziness, lightheadedness, or confusion
- Heart palpitations
- Rapid pulse
- Shortness of breath
- Weakness, fatigue, or a decline in the ability to exercise
