WebThe three waves of the QRS complex represent ventricular depolarization. For the inexperienced, one of the most confusing aspects of ECG reading is the labeling of these waves. The rule is: if the wave immediately after the P wave is an upward deflection, it is an R wave; if it is a downward deflection, it is a Q wave: WebApr 14, 2024 · Electrocardiographic abnormalities may be confined to the upslope, the top, or the downslope of the R wave. Such changes may occur as isolated abnormality or may …
WebQ wave represents the depolarization of the interventricular septum. It is represented as a small downward deflection. The P-wave is immediately followed by a Q-wave. Abnormality in Q-wave indicates the presence of infraction. R-wave The Q is followed by R-wave. This wave follows as an upward deflection. The R is then followed by an S-wave.
