An electrocardiogram ( ECG or EKG ) is a simple, noninvasive, painless test that records the heart's electrical activity over a period of time using electrodes placed on a patient's body. Your doctor may recommend an EKG if you’re experiencing symptoms or signs that may suggest a heart problem, including: pain in your chest trouble breathing feeling tired or weak pounding, racing or fluttering of your heart a feeling that your heart is beating unevenly detection of unusual sounds when your doctor listens to your heart If you have a family history of heart disease, your doctor may suggest an electrocardiogram as an early screening test, even if you have no symptoms. EKG leads are attached to the body while the patient lies flat on a bed or table. Make sure to lie as still as possible and breathe normally. You shouldn’t talk during the test. The test takes about five minutes. In some instances, men may require the shaving of a small amount of chest hair to obtain optimal contact between the leads and the skin. Sometimes EKG abnormalities can be seen only during exercise or while symptoms are present. To check for these changes in the heartbeat, a stress EKG may be done, and you will be asked to walk or run on a treadmill or cycle on an exercise bike while your heartbeat is recorded. No special preparations are necessary. However, tell your doctor about any medications or supplements you're taking. Some medications and supplements may affect the outcome of your electrocardiogram.
