A quick painless test to assess heart rate, rhythm, and electrical impulses.
An electrocardiogram or ECG (EKG) is a quick and painless heart tracing which helps to assess how well the heart is functioning by looking at heart rate, rhythm and electrical impulses. If a person has chest pain or palpitations, an ECG is helpful in determining if the heart is performing normally.
There are no restrictions for food or fluids. Exercise (such as climbing stairs) immediately before an ECG may significantly increase your heart rate.
You will be asked to lie down, and self-adhesive electrodes are affixed to your arms, legs and chest. You are usually required to remain still, and you may be asked to hold your breath for short periods during the procedure.
