WebA detailed view of the QRS complex (Q-wave, R-wave and S-wave) with emphasis on normal findings, amplitudes, durations / intervals, pathology. WebJul 13, 2024 · 1) Left ventricular activation via the left bundle (black arrow) occurs normally. 2) Septal depolarisation (yellow arrows) is thus unaffected, producing a normal early QRS complex. 3) Activation of the RV originates across the septum. The resultant depolarisation vector (red arrow) produces delayed R waves in leads V1-3, and S waves in lateral ...
