The normal adult QRS axis is between -30 degrees and +90 degrees, which is directed downward and to the left. This adult range is sometimes extended from -30 degrees to +100 degrees.
NettetIn this condition there is a swing of the cardiac axis to the left - ie less than minus 30 degrees. It is usually the result of a left anterior hemiblock rather than to the increased bulk of muscle of the left ventricle.
