ECG changes in right ventricular hypertrophy (RVH)
Last reviewed 01/2018
Features of the ECG in right ventricular hypertrophy include:
- right axis deviation
- possibly a predominant R wave in lead V1 - in a normal ECG the S wave is dominant in V1
- there will be a deep S in V6 - in a normal ECG the QRS complex is predominantly upwards in V6
- inverted T waves in right praecordial leads - V2, V3 - will be present in severe cases; it is normal to have inverted T waves in V1
- peaked P waves may also occur due to right atrial hypertrophy
- QRS < 0.12s
