Practice Question # 662.


Premature ventricular contractions


  • Early ventricular contractions result from increased irritability of the ventricles.
  • PVCs frequently occur in repetitive patterns such as bigeminy, trigeminy, and quadrigeminy.
  • The QRS complexes may be unifocal or multifocal.


  • Identify the cause and treat on the basis of the cause.
  • Evaluate oxygen saturation to assess for hypoxemia, which can cause PVCs.
  • Evaluate electrolytes, particularly the potassium level, because hypokalemia can cause PVCs.
  • Oxygen and medication may be prescribed in the case of acute myocardial ischemia or MI.
