Answer

Stress testing is an ancillary test and may be used (1) to reproduce a transient paroxysmal SVT (PSVT), which is triggered by exercise, (2) to document the relationship of exercise to the onset of tachycardia, or (3) to evaluate the efficacy of antiarrhythmic drug therapy (class Ic antiarrythmic medications and effects on antegrade preexcitation).
