The graph records every electrical phase of the heartbeat, and each beat is triggered by pacemaker cells. A EKG not only records the electrical phase, but it records the strength and timing of every impulse generated from the upper right chamber of the heart. Each of these recordings can be quickly and easily evaluated to determine whether or not there is an abnormality but this can only be recorded if the abnormality is recorded during the test.
