Right ventricular hypertrophy on ECG is usually associated with which axis deviation?

Right ventricular hypertrophy increases the right-ward electrical forces of the heart, shifting the overall direction of depolarization toward the right. This shows up on the ECG as right-axis deviation, with the QRS axis typically between +90 and +180 degrees. In limb leads, you may see a negative QRS in lead I and a positive QRS in lead aVF, reflecting the rightward shift. Clinically, RVH often also presents with tall R waves in the right precordial leads (V1–V2) and deeper S waves in the left precordial leads (V5–V6). So the association is right-axis deviation.
