Stress testing is ancillary and may be used for the following:

  • To reproduce a transient paroxysmal SVT, which is triggered by exercise
  • To document the relationship of exercise to the onset of tachycardia
  • To evaluate the efficacy of antiarrhythmic drug therapy (class Ic antiarrhythmic medications and effects on antegrade preexcitation)
  • To determine whether consistent or  intermittent preexcitation is present at different sinus (heart) rates
