WebApr 14, 2024 · RBBB with left anterosuperior fascicular block is diagnosed when precordial leads show features of RBBB but limb leads show some features of left anterosuperior fascicular block like frontal plane QRS axis of −45 0 to −90 0 and rs configuration in leads II, III, and aVF. However, unlike pure RBBB, lead I shows tall R without s wave. WebApr 13, 2024 · Coronary sinus lead = epicardial to LV. LV and RV may depolarize nearly at same time (resynchronizing the ventricles). Usually LV depolarizes first, followed by RV. EKG will usually result in RBBB-like morphology: wide QRS, tall R in V1, deep S in lateral leads. RA lead. EKG will show pacing spikes with relation to p-waves (either before or after)
