QRS

Detailed explanation-1: -the S wave signifies the final depolarization of the ventricles, at the base of the heart.
Detailed explanation-2: -In general, a positive QRS complex in a lead has a ventricular axis that is approximately in the same direction going to that lead. Whereas a negative QRS complex in a lead has a ventricular axis that is approximately in the opposite direction to that lead.
Detailed explanation-3: -The largest wave in the QRS complex is the R wave. Image: R Wave. As you can see from the diagram, the R wave represents the electrical stimulus as it passes through the main portion of the ventricular walls.
Detailed explanation-4: -The P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.
