Detailed explanation-1: -The QRS complex represents the depolarization of ventricles. It shows the beginning of systole and ventricular contraction. The QRS complex or wave starts with a small deflection downwards, represented by the point Q. It follows the P wave.
Detailed explanation-2: -The QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).
Detailed explanation-3: -On the ECG, all waveforms can be categorized into two groups: depolarization and repolarization. Ventricular depolarization is depicted by the QRS complex, and ventricular repolarization is represented by the J (Osborn), T, and U waves.
Detailed explanation-4: -QRS represents ventricular depolarization.
