It is a polymorphic ventricular tachycardia that exhibits distinct characteristics on the ECG recording of ventricular repolarization (T wave).
4 Oct 2011 The current study aimed to evaluate the effect of severe CoA on the heterogeneity of ventricular repolarization by examining corrected QT and
C) ventricular depolarization. D) ventricular repolarization. E) ventricular contraction. The mean electrical axis represents the sum of all of the mean electrical vectors occurring during ventricular depolarization. The mean electrical axis is depicted by a green arrow in the figure to the right, which shows the same instantaneous mean vectors as in the figure at the top of this page but superimposed upon the axial reference system. Early repolarization of the ventricles — electrocardiographic syndrome, reflected in the electrocardiogram in the form of a sawtooth end of the R-wave and to lift above the contour of the ST segment.
This repolarization process occurs in the muscle of the ventricles about 0.25 second after depolarization. There are, therefore, both depolarization and repolarization waves represented in the electrocardiogram. The atria repolarize at the same time that the ventricles depolarize; however, the atrial repolarization wave is obscured by… Read More Background: Both duration and morphology of the T-wave are regarded important parameters describing repolarization of the ventricles. Conventionally, T-wave concordance is explained by an inverse relation between the time of depolarization (TD) and repolarization (TR). Se hela listan på ahajournals.org Does repolarization mean relaxation? Initially, both the atria and ventricles are relaxed (diastole). The QRS complex represents depolarization of the ventricles and is followed by ventricular contraction.

Secondary repolarization abnormalities In secondary repolarization abnormalities the depolarization of the ventricles is abnormal in some way, which causes the ventricular repolarization to be abnormal as well as a result. Conditions with secondary repolarization abnormalities:

After depolarizing (contracting) both the atria and the ventricles, it is now time to repolarize (relax) them. So, as Ventricular Repolarization occurs, a bump known as the T Wave is created on the graph. Atrial Repolarization occurs at the same time as Ventricular Repolarization, but there is no wave to represent it as the T Wave covers it.
