Why is the QRS complex so large?
Depolarization of the atrial myocardium (major heart muscles are signaled to contract)
Repolarization of the ventricular myocardium (major heart muscles are relaxing)
Repolarization of the atrial myocardium (major heart muscles are relaxing)
Depolarization of the ventricular myocardium (major heart muscles are signaled to contract)
Homework Answers
1) The QRS complex shows the depolarization in the muscles of ventricles.As the muscles of ventricles have large mass of muscles than atria , the amplitude of QRS complex is so large.
2) Depolarization of the atrial myocardium is shown by P wave.
3) Repolarization of the ventricular myocardium is shown by T wave.
4) Repolarizaton of the atrial myocardium is not shown by ecg as the amplitude of atrial relaxation is very low.It starts from the end of the P wave and continues till the complete cycle(repolarization of ventricular myocardium)
5) Depolarization of ventricular myocardium is shown by QRS complex.
