C. Left bundle branch block – Explanation
LEFT BUNDLE BRANCH BLOCK (LBBB)
It is always good to be able to recognise a LBBB on an ECG
LBBB is best seen in lead V6, where you would see a broad complex with an “M”
morphology.
This broad complex “M” morphology can also be seen in leads I and aVL
Other ECG features of LBBB include:

LBBB is best seen in lead V6, where you would see a broad complex with an “M”
morphology.
This broad complex “M” morphology can also be seen in leads I and aVL
Other ECG features of LBBB include:
- Left axis deviation
- Deep S-wave in V1
Below are some ECG examples with LBBB seen
- Broad complex “M” morphology seen in leads I and aVL
- Broad complex in V6
- Deep S-wave in V1
- Broad complex “M” morphology seen in leads I
- Broad complex in V6
- Deep S-wave in V1
