Intraventricular conduction delay (IVCD) is a critical ECG finding, marked by a widened QRS complex (≥120 ms), reflecting delayed electrical conduction within the ventricles. Left bundle branch block (LBBB) is characterized by a deep S wave in lead V1, broad, single-peaked R waves in lateral leads (I, aVL, V5-V6), and a delayed R wave peak time (>60 ms in V5-V6), indicating left ventricular conduction impairment. Conversely, right bundle branch block (RBBB) presents with a QRS duration exceeding

Alireza sadeghi on Instagram: "Right bundle branch block is an intraventricular conduction abnormality in which interruption or delay of impulse propagation through the right bundle branch causes the left ventricle to depolarize normally first, followed by delayed right ventricular activation via cell-to-cell conduction, producing a QRS duration ≥120 ms with an rSR′ or rsR′ pattern in V1–V2, broad terminal S waves in leads I, aVL, and V6, and secondary right precordial ST-T changes. #paramedic #
