ECG Axis Determination
Thomas E. O'Brien
AS CCT CRAT RMA
Upon completion of the accompanying narrative and practice the student will be able to:
- Recall which major coronary artery supports each region of the heart
- Associate the views of a 12-Lead ECG with specific surfaces of the heart
- Determine the presence of cardiac axis deviation
People may choose to analyze ECG’s in a number of different ways. The sequence doesn’t necessarily matter as long as you gather and report the proper information each time. I read from left to right as much as possible (in anatomic groupings).
If your protocols are different, always follow them.
The following slides will review the leads, surfaces, and associated coronary arteries which commonly supply that portion of the heart.
