WebNov 22, 2024 · qRs: small initial non-pathological Q wave, followed by a tall R wave and a small S wave. On a normal electrocardiogram, it can be seen in leads V5 and V6. RS: tall R wave followed by a deep S wave, with similar amplitude (biphasic QRS). It is the characteristic morphology in lead sV3. rS: small R wave followed by a deep S wave. Webnotch in the descending limb of the R-wave and/or notch in the descending limb of the S-wave In case of complete/incomplete bundle branch block or pacemaker rhythm, >2 notches are required in the S-wave or R-wave.
