Axis & Deviation ECG Interpretation #322


Description

  • Axis is the general flow of electricity as it passes through the heart from the SA node all the way to the Purkinje fibers.
  • It is typically obtained from the limb or frontal plane leads.
  • The axis of the heart can change for a number of different reasons from birth defects which affect the physical location of the heart i.e. Dextrocardia, to obesity to pregnancy among others.
  • If you can envision a circle with a centered vertical and horizontal line superimposed over the chest, you would note that the normal heart is located in the lower left quadrant of this circle.
  • You will be provided an example of this image in a few slides.
