ECG
An electrocardiogram (ECG) is a simple test that can be used to check your heart's rhythm and electrical activity. This can also help to identify abnormal heart rhythms, a previous heart attack or problems with the heart muscle.
ECGs are often done in a doctor's office, a clinic or a hospital room.
An ECG is a noninvasive, painless test with quick results. During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes your limbs. These sensors are usually left on for just a few minutes. Sometimes, it may be necessary to shave a gentleman’s chest in order to apply the electrodes.
Your doctor may discuss your results with you the same day as your electrocardiogram or at your next appointment.
