WebThe QRS complex reflects the depolarization (activation, contraction) of the ventricles. Although it may not always include a Q-wave, R-wave and S-wave, it is still referred to as a QRS complex. In other words, if ventricular depolarization only generates a Q-wave and an R-wave, that complex may still be referred to as a QRS complex.
