Course Sample:
Why look to the EKG?
The electrocardiogram (EKG) is a device that receives electric impulses from the body and changes them into a monitor tracing that can be analyzed to find problems with electrical conduction in the heart. The EKG simply picks up electrical impulses; it does not read mechanical activity. When a patient has ischemia, injury or necrosis to the heart muscle, the electrical impulses change in the area involved. Nurses can analyze the electrical changes and determine if they indicate mechanical dysfunction.
Why use 12-Leads?
Traditional EKG monitoring is done with a single lead to assess for arrhythmias. However, a single lead provides only a single view of the heart. Consider the following analogy: if you were buying a house and wanted to show your friends what it looked like, a picture would give them some idea of the size and shape of the house. One picture wouldn't show the sides or the back of the house, nor would it represent the layout of the house on the land it is on. Several pictures would do a much better job.
Single lead EKG: one view
Limb leads: walking around the heart
Lead Placement of Limb Leads
Four electrodes are placed on the patient's chest, in the direction for the four limbs, as illustrated below in Figure 1. The brown lead is used as a chest lead when monitoring the patient.
Figure 1
The augmented limb leads (AVR, AVL, AVF): use these leads to assess cardiac activity from different perspectives. The limb leads "walk around the heart" and can be used to determine the direction the electrical impulse is traveling across the myocardium.
Chest leads: flying over the heart
If you were to walk around the house and take pictures, you could show the back and sides of the house. How about an aerial photo? That would really show the lay of the land! These are the concepts behind the 12-lead EKG: the limb leads walk around the house, while the chest leads give the aerial view. By using twelve different views, many different parts of the heart can be assessed.
