Correct answers

  • The PR interval is greater than 0.20 seconds
  • The QRS complex is wider than 0.12 seconds
  • It is polymorphic
  • There is no organized rhythm — the rhythm represents a cardiac arrest
  • There is no electronical activity or a heart rate less than 15 per minute
  • The impulse originates in the ventricle and so is wide
  • PR intervals that lengthen until a QRS complex is dropped, it has 'groups of beats'
  • Consistent PR intervals, but not always conducted. There are more P waves than QRS complexes
  • No two PR intervals are the same, the atrial rhythm is regular, the ventricular rhythm is regular but they have nothing to do with each other
