3. What is Axis?

5. The quadrant method (AKA thumbs up method)
Left thumb is Lead I
Right thumb Lead aVL

10. Right Axis deviation differential diagnosis
Left posterior fascicular block
Lateral MI
RVH PE
COPD
Hyperkalemia
WPW

14. Left Axis Deviation differential diagnosis
Left anterior fascicular block
Bifascicular block
Left bundle branch Block
LVH
Inferior MI
Ventricular ectopy
WPW

15. Why is axis important?

16. Why is axis important? It may help you differentiate certain rhythms
It can help support a diagnosis
It is necessary for diagnosis of LAFB, LPFB, bifascicular block and trifascicular block

19. Left anterior fascicular block
-Left axis
-Small Q wave I and aVL
-Small R waves II, III, aVF
-Normal QRS duration
-Prolonged R wave peak time
In aVL

22. Bifascicular block
