Is an electrocardiogram (ECG) painful?

An electrocardiogram (ECG) is painless. It measures the natural electrical activity in your heart, but no outside electricity is sent through your body during the test.

If there is any discomfort at all, it comes from the need to apply sticky electrode patches to your chest, arms and legs. Removing the patches is like pulling off a small bandage. Some people who are allergic to tapes or adhesives may develop a skin rash in the area.

An electrocardiogram (ECG) is a painless procedure. It is a non-invasive procedure that measures the electrical impulses of a person's heart to see if there are any abnormalities. Electrodes (sticky patches) are placed on the chest, arms and legs with wires attached to the ECG machine. It does not result in pain or discomfort to the patient. When the electrodes are removed there may be some discomfort due to the adhesive on the back being pulled away from the skin. Similar to when a band aid is pulled off the skin.
