5.2 Right ventricular hypertrophy


Right ventricular hypertrophy is associated with pulmonary hypertension, mitral stenosis, and, less commonly, conditions such as pulmonary stenosis and congenital heart disease

The forces generated by right ventricular depolarization are directed rightwards and anteriorly and are almost completely masked by the dominant forces of left ventricular depolarization. In the presence of right ventricular hypertrophy the forces of depolarization increase, and if the hypertrophy is severe these forces may dominate on the electrocardiogram.
