The cardiac axis Right Axis Deviation and Left Axis Deviation Causes and Treatment

The cardiac axis is the resultant direction of the flow of current of depolarization through the heart.

  • The normal axis of heart is the range from –30 degree to +90 degree,
  • In Heart with normal axis Lead I and Lead III will have positive QRS, in Left Axis Deviation Lead I will have negative QRS,
  • Cardiovascular System examination, cardiac disorders
  • While in right axis Deviation Lead I will have negative QRS and Lead III will have positive QRS.
