The ECG is a recording of the electrical activity of the heart. Patches (electrodes) are placed on the chest, arms and legs to detect the information.
The test is used to:
- Assess your heart rate and rhythm
- Diagnose poor blood flow to the heart muscle (ischemia)
- Diagnose a heart attack
- Diagnose abnormalities of your heart such as heart enlargement or abnormal electrical conduction
Preparing for the test:
- Avoid skin creams and lotions the day of the test. They prevent the patches from sticking to the skin.
- Avoid full-length hosiery, as the patches need to be placed directly on the legs.
- Wear a shirt that can be easily, as the patches need to be placed directly on the chest and arms.
What to expect during the test:
A technician will attach 10 sticky patches (electrodes) to the skin of your chest, arms and legs. Men may need to have chest hair shaved to allow a better connection. You will lie flat while the computer creates a picture of the electrical activity produced by your heart.
It takes about 10 minutes to attach the patches and complete the test, but the actual recording takes only a few seconds.
Your ECG will be kept on file for comparison with future ECG recordings.
What to expect after the test:
This test is typically performed during your scheduled office exam. The doctor will discuss the results of the ECG with you during your visit.
