In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
A QRS wave is caused by the depolarization of the ventricles of the heart, which leads to the contraction of the ventricles and the pumping of blood out of the heart. The QRS complex represents the electrical activity associated with this depolarization.
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
The T wave in an ECG is typically in the same direction as the QRS complex because both represent ventricular depolarization and repolarization, respectively. During the QRS complex, the ventricles depolarize, and then during the T wave, they repolarize, leading to the similar orientation of the waves.
There are a number of things that may happen during the QRS wave. There will be ventricular depolarization and right after absolute refractory period for ventricles will occur.
