Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.

  • The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex.
  • It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.
  • An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex.
  • The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.
  • An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.
