WebNov 16, 2024 · The two major phases of cardiac electrical activity are depolarization and repolarization. When a cell depolarizes, a positive charge enters the cell, causing it to become less negative. Because of this deflection, the ECG trace is positive. When a cell is repolarized, its negative potential returns to its resting state. WebThe ECG machine processes the signals picked up from the skin by electrodes and produces a graphic representation of the electrical activity of the patient's heart. The basic pattern of the ECG is logical: electrical activity towards a lead causes an upward deflection. electrical activity away from a lead causes a downward deflection.
