What are the components that we measure on a P, Q, R, S, T? Make sure you can draw and label them correctly!

CLASS, THIS CONTENT ON THE MEAN QRS IS NOT ON THE FIRST EXAM but will be on the SECOND EXAM.
How do you determine the mean QRS? Practice, Practice Practice! What leads do you use? What steps do you follow?
When measuring the QRS axis, where is your actual starting point on the heart to find this Mean Vector? (i.e., SA Node, AV Node, Bundle of His, Bundle branches, Purkinje fibers) (Answer, it is the AV node).
What is the range for a normal QRS axis (from what degrees to what degrees)? What is the range for right axis deviation? What is the range for extreme right axis deviation? What is the range for left axis deviation?
When reporting the mean QRS, how is this correctly done? EKG Page
