Authoring team

  • ventricular tachycardia
  • supraventricular tachycardia (SVT) with pre-existing bundle-branch block
  • SVT with aberrant conduction

  • antidromic atrioventricular reentry - in this case the anomalous pathway is part of the circuit and conducts the impulse from atria to ventricles
