An EKG is a test of electrical activity of the heart and should only be viewed in conjuction of other tests, symptoms and signs.
Left axis deviation indicates that a particular quadrant portion of the heart is not within the normal range measured in degrees.
It can be a harmless observation caused by medication, excessive potassium, an abnormal valve that separates the right atria and right ventricle, it can be a block of the right-side pathway for a electrical pulse to pass (could cause arrhythmia) or it could indicate heart muscle damage from an MI (heart attack). Worst case scenario.
Often with an EKG there are artifacts. An ideopathic and stray signal shows up on the gragh that is harmless and cause unknown. Other tests are required!
