What is an electrocardiogram?
An electrocardiogram is a simple, painless test that measures the electrical activity of your heart. An electrocardiogram is also known as an ECG or EKG. Each heartbeat is triggered by an electrical signal that starts at the top of your heart and travels down.
What is an electrocardiogram or EKG?
Heart problems often affect the electrical activity of your heart. Your doctor may recommend an ECG if you have signs or symptoms that may indicate a heart problem, such as:
- Hearing unusual sounds when your doctor listens to your heart
- Difficulty breathing, feeling tired or weak
- Palpitations, racing or fluttering of the heart
- Feeling like your heart is beating irregularly
- Chest pain
What happens during an ECG? Types of ECG or Electrocardiogram:
An ECG is quick, painless, and harmless. After getting into the suit, the technician will attach 12 to 15 soft, gel-covered electrodes to your chest, arms, and legs. He or she may have to scrape small areas to make sure the electrodes are properly attached to your skin. Each electrode is about the size of a dime. These electrodes are connected to wires (leads), which are connected to an ECG machine. During the test, you’ll lie on a bed while the machine records your heart’s electrical activity and plots the information on a graph. Make sure to lie as still as possible and breathe normally. You shouldn’t talk during the test. After the procedure, the electrodes are removed and discarded. The entire procedure takes about 10 minutes.
An ECG records a picture of your heart’s electrical activity while you are monitored. However, some heart problems are not permanent. In these cases, you may need more specialized or longer monitoring
