The QRS complex represents the electrical impulse as it spreads through the ventricles and indicates ventricular depolarization. As with the P wave, the QRS complex starts just before ventricular contraction. It is important to recognize that not every QRS complex will contain Q, R, and S waves.
What is masked on an ECG by the QRS complex?
The QRS complex is a result of ventricular depolarization and indicates the start of ventricular contraction. The T wave results from ventricular repolarization and signals the beginning of ventricular relaxation. The electrical signal for atrial repolarization is masked by the larger QRS complex.
What are the atria and ventricles doing during the QRS complex?
The atria contract (squeeze), pumping blood into the ventricles, and then immediately relax. The electrical impulse then reaches the ventricles. This can be seen in the Q, R and S waves of the ECG, which is called the QRS complex. The ventricles contract.
