Right ventricular hypertrophy

ECG Findings

RVH

RVH in 12-lead ECG

• RVH is usually associated with right atrial enlargement or right ventricular strain (deep ST inversions in leads V1-V3)
• Dominant R in V1 >7mm
• RSR in V1 with QRS < 0.12

These criteria are less sensitive and specific than LVH criteria

Differential Diagnosis

Cardiac Hypertrophy and Enlargement

• Right atrial enlargement
• Left atrial enlargement
• Left ventricular hypertrophy
• Right ventricular hypertrophy

R > 7mm in V1

• WPW
• RBBB
• Right ventricular hypertrophy
• Posterior MI
• Normal Variant
