QRS in V1
Last reviewed 01/2018
The examination of the QRS complex ought to be finished with a specific look at V1, which should be mainly S waveform
If R is dominant then this may be caused by:
- right bundle branch block
- right ventricular hypertrophy
- posterior MI
- Wolf Parkinson White syndrome (type A). The latter condition is also characterised by delta waves, a shoulder or slurred upstroke in the QRS complex (1)
- dextrocardia
- Duchenne's muscular dystrophy
- normal variant
