You need more force to pump the blood to the lungs or the body than you do just to pump it to the next chamber.
The atria pump to the ventricles. Easy. The ventricles need to pump the blood to the lungs (right ventricle) or the body (left ventricle) which calls for more pressure, hence a larger contraction wave.

Which wave is larger the one for atrial contraction or the one for ventricular contraction?
Ventricular contraction wave is larger
Why is the ventricular wave higher?
Assuming you are talking about Electrocardiogram readings, the ventricular contraction is represented by the 'R' wave. The R wave is so much higher because the left and right ventricles are made up of the largest and strongest muscles of the heart and show the largest electrical energies on the ECG when they are contracted.
How many seconds does ventricular contraction last?
The normal time of ventricular contraction depends on the heart rate. The QT segment represents the ventricular contraction on an ECG exam. The corrected QT segment is 0.45 seconds for men and 0.46 seconds for women.
What is the ventricular contraction period?
This is called the systole :)
How long is the ventricular contraction period?
0.3 Seconds
Which wave length is larger atrial contraction or ventricular contraction?
the ventricular contraction wave is larger
Which wave is larger the one for atrial contraction or the one for ventricular contraction?
Ventricular contraction wave is larger
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
What does a inverted QRS wave indicate?
In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
Is the pulse caused by the expanding and narrowing of the artery walls?
No. The pulse is caused by the pressure wave resulting from ventricular contraction.
Where on the cardiac cycle does a synchronized shock land?
A synchronized cardioversion shock is delivered a few milliseconds after the R wave on the EKG. The R wave represents ventricular depolarization, which is followed by mechanical contraction of the ventricle. Therefore, it can be seen that a synchronized shock will occur during ventricular contraction, or during ventricular systole, to completely depolarize the myocardium and try to restore a normal rhythm.
What part of an ECG represents ventricular depolarization?
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
What does inadequate ventricular systole mean?
It is a defective ventricular contraction.
Why is the ventricular wave higher?
Assuming you are talking about Electrocardiogram readings, the ventricular contraction is represented by the 'R' wave. The R wave is so much higher because the left and right ventricles are made up of the largest and strongest muscles of the heart and show the largest electrical energies on the ECG when they are contracted.
What does ventricular repolarization result in?
contraction
How many seconds does ventricular contraction last?
The normal time of ventricular contraction depends on the heart rate. The QT segment represents the ventricular contraction on an ECG exam. The corrected QT segment is 0.45 seconds for men and 0.46 seconds for women.
What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
