Which component of the ECG cycle shows ventricular depolarization?
|
|
P
|
|
|
QRS
|
|
|
T
|
|
|
U
|
Explanation:
Detailed explanation-1: -The three waves of the QRS complex represent ventricular depolarization.
Detailed explanation-2: -Ventricular depolarization (activation) is depicted by the QRS complex, whereas ventricular repolarization is defined by the interval from the beginning of the QRS complex to the end of the T-or U-wave. On the surface ECG, ventricular repolarization components include the J-wave, ST-segment, and T-and U-waves.
