EKG (also ECG) is an abbreviation for electrocardiogram. EKGs are used to detect possible heart conditions by measuring the electrical activity of the heart.
How are EKGs Performed?
In an EKG, leads are attached to the body while the patient lies flat on a bed or table. Four leads are attached to each extremity and to six specific areas on the chest. A small amount of gel is applied to the skin allowing the electrical impulses of the heart to be easily transmitted to the leads. The leads are attached by small adhesive patches attached to the skin. The test takes about five minutes and is painless.
