WebNov 18, 2024 · In contrast, RBBB primarily affects the terminal phase of ventricular depolarization, producing a wide R' wave in the right chest leads and a wide S wave in the left chest leads (waveform 1A-B). These changes are due to delayed depolarization of the right ventricle, while depolarization of the left ventricle is not substantially affected.
