But none of their patients with SVT had a preexisting RBBB. Webb10 nov. 2024 · “In the normal heart, the general direction of ventricular depolarization is in a right-to-left, downward direction because of the larger mass of the left ventricle compared with the right ventricle. This results in a characteristic appearance of the QRS complex in lead V1 of the ECG, the rS configuration.
