    • Diagnosing Right Ventricular Hypertrophy

      Right ventricular hypertrophy (RVH) is the abnormal enlargement of the right ventricle in response to pressure overload, most commonly due to severe lung disease. The right ventricle is considerably smaller than the left ventricle and produces electrical forces that are largely obscured by those generated by the larger left ventricle.

There is a resulting variable right-to-left shunt of deoxygenated blood, due to the dynamic right ventricular outflow tract obstruction.
