(2) QRS wave (complex). This second wave begins as a downward
deflection and continues as a large, upright, triangular wave which finally ends as a
downward wave at its base. This wave complex shows the spread of the electrical
impulse through the ventricles.
(3)
T wave. The third wave showing ventricular repolarization.
NOTE:
There is no deflection to show atrial repolarization because the stronger QRS
wave masks this event.
NOTE:
Figure 2-5 shows EKG wave patterns produced by the electrical activity of
the heart.
