During the test, the doctor will put small metal discs called electrodes, these electrodes are connected to wires connected at the same time to a machine with a screen that register all electrical activity of your heart.

Looking at the screen, doctors may register the heartbeats while the patient exercise.

Those very ill patients that may not be able to do exercise receive medication that simulate the effects of physical exercise in the organism.
