Web1 de jan. de 2006 · The normal range of the mean electrical axis in dogs is +40 to +100 degrees and in cats is 0 to +160 degrees ( Figure 1 ). In dogs, a right axis shift is defined as a mean electrical axis between +100 and -90 degrees. In cats, a right axis shift occurs when the mean electrical axis is between +160 and -90 degrees. WebNormal q-waves reflect normal septal activation (beginning on the LV septum); they are narrow (<0.04s duration) and small (<25% the amplitude of the R wave). They are often seen in leads I and aVL when the QRS axis is to the left of +60°, and in leads II, III, aVF when the QRS axis is to the right of +60°.
