WebFeb 2, 2024 · The ratio of P waves to QRS complexes should be 1:1 in a normal rhythm (discussed in more detail in the next segment). Noting a P to QRS ratio that is different from a 1:1 ratio will help you discern certain rhythms. 3. Do the P waves come at consistent intervals or “march out”? The QRS complexes? WebRegardless of which waves are visible, the wave(s) that reflect ventricular depolarization is always referred to as the QRS complex. Naming of the waves in the QRS complex: The …
WebMar 5, 2024 · The three waves of the QRS complex represent ventricular depolarization. the R wave reflects depolarization of the main mass of the ventricles –hence it is the largest wave. the S wave signifies the final depolarization of the ventricles, at the base of the heart.
