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. dr rashley statesville ncWebSuch a measurement is called an electrocardiogram (EKG or ECG).
