WebJul 13, 2024 · Sequence of conduction in RBBB: 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 ... WebThe QT dispersion (QTd) on ECG indicates ventricular repolarization and depolarization. Increased QTd is an indicator of ventricular instability, which thus may lead to severe ventricular arrhythmia and sudden cardiac death. 21, 22 P-wave dispersion (Pd) is defined as the difference between the widest and the narrowest P-wave duration on ECG ...
