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)
Right bundle branch block (RBBB): ECG, criteria ... - ECG & ECHO
WebBackground: Permanent pacemaker implantation (PPI) after transcatheter valve implantation (TAVI) is a common complication. Pre-existing right bundle branch block (RBBB) is a strong risk factor for PPI after TAVI. However, a patient-specific approach for risk stratification in this subgroup has not yet been established. Methods: We investigated … WebJan 30, 2014 · The T wave is normally upright in leads I, II, and V2 to V6; inverted in lead aVR; and variable in leads III, aVL, aVF, and V1. In general, an inverted T wave in a single lead in one anatomic segment (ie, inferior, lateral, or anterior) is unlikely to represent acute pathology; for instance, a single inverted T .
