the ventricular contraction wave is larger
Ventricular contraction wave is larger
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.
It is a defective ventricular contraction.
It is a lengthening of the amount of time between depolarization of the ventricles of the heart, and the repolarization of the ventricles of the heart. The significance of this lies in the fact that the Q-T interval is a vulnerable time for the heart. Stimulation of the heart muscle during the relative refractory period (which is during the latter part of the Q-T interval) will cause a premature ventricular contraction, which may throw your heart into a dangerous dysrhythmia.
contraction
purkinjie fiber develops a rhythm of its own & ventricular contraction occur
This is called the systole :)
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
QT interval
A group of premature ventricular contractions in which the QRS configuration is always the same are referred to as monomorphic premature ventricular contractions.
