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
