12-Lead ECG
-
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.
