Naming of the waves in the QRS complex is easy but frequently misunderstood. The following rules apply when naming the waves: 1. A deflection is only referred to as a waveif it passes the baseline. 2. If the first wave is negative then it is referred to as Q-wave. If the first wave is not negative, then the QRS complex does … See more The QRS complex can be classified as net positive or net negative, referring to its net direction. The QRS complex is net positive if the sum of the positive areas (above baseline) exceeds that of the negative areas (below … See more Depolarization of the ventricles generate three large vectors, which explains why the QRS complex is composed of three waves.

WebThe QRS complex indicates ventricular depolarization. The QRS interval is measured from the end of the PR interval to the end of the S wave. The rule is: if wave immediately after P wave is an upward deflection, it is an R wave; if it is a downward deflection, it is a Q wave:-small Q waves correspond to depolarization of the interventricular septum. WebAug 23, 2024 · The QRS wave is sometimes called the QRS complex, and it represents the depolarization of the ventricles.
