How Is an Electrocardiogram Performed?
An electrocardiogram (ECG or EKG) is performed by placing small, adhesive electrodes on the patient's chest, arms, and legs. These electrodes are connected to an ECG machine via wires and work by detecting the electrical signals generated by the heart each time it beats. The patient is usually required to lie flat while the machine records the heart's rhythm and electrical activity. The process is quick, non-invasive, and painless, typically taking only a few minutes to complete. The machine prints the data in the form of waves on graph paper or displays it on a screen for the physician to review.
Before the test, the area where the electrodes will be placed may be cleaned and, if necessary, shaved to ensure that the electrodes adhere properly and to provide accurate readings. It's important for the patient to remain still and breathe normally during the test, as movement can interfere with the electrodes and lead to inaccurate results. The procedure does not involve any exposure to radiation and there are no risks directly associated with performing an EKG itself.
