The direction of the wave of contraction in the heart is important because it decides where the blood reflux will take place. The blood reflux could take place in the atria, or the blood from the heart could be ejected into the pulmonary artery or aorta.
The T wave represents ventricular repolarization in the heart's electrical cycle. It indicates the recovery of the ventricles, preparing them for the next contraction. Changes in the T wave can sometimes signify heart abnormalities.
The R wave in an electrocardiogram (ECG) represents the depolarization of the ventricles in the heart. It is a measure of the electrical activity during the contraction phase of the heart's pumping cycle.
The PQRS wave represents the electrical activity in the atria of the heart during an electrocardiogram (ECG). The P-wave indicates atrial depolarization, which is the contraction of the atria.
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 wave for ventricular contraction is larger than the wave for atrial contraction. This is because the ventricles have thicker muscle walls and contract more forcefully in order to pump blood out to the body.

the atria contracts first then the ventricle hencep qrs
i did not understand your question well, but there are three wave in working heart i a second: 1-P wave:its about 0.1 second and contraction of the Atriums 2-QRS wave: its about 0.4 second and contraction of the bellies. 3-T wave:its about 0.5 second and relaxing of the heart..

the ventricular contraction wave is larger

No, depolarization is not the resting state of the P wave. Depolarization is the process where the heart muscle contracts in response to an electrical signal. The P wave represents atrial depolarization, the electrical activity that triggers the contraction of the atria in the heart.
In a transverse wave, the direction of wave propagation is perpendicular to the direction of the wave oscillation.
The P wave corresponds to the atrial contraction... the 'beat' of the upper chambers of the heart. The QRS complex correponds to the ventricular contractoins.. the 'beat' of the other two chambers. The T wave represents relaxation of the heart muscle.
