Answer

Relative indications for termination include the following:

  • Drop in SBP of 10 mm Hg or more from baseline, despite an increase in workload, in the absence of other evidence of ischemia

  • ST or QRS changes such as excessive ST depression (horizontal or downsloping ST-segment depression >2 mm) or marked axis shift

  • Arrhythmias other than sustained ventricular tachycardia, including multifocal premature ventricular contractions (PVCs), triplets of PVCs, supraventricular tachycardia, heart block, or bradyarrhythmias

  • Fatigue, shortness of breath, wheezing, leg cramps, or claudication

  • Development of bundle branch block or intraventricular conduction delay that cannot be distinguished from ventricular tachycardia

  • Increasing chest pain

  • Hypertensive response (SBP of 250 mm Hg, diastolic blood pressure [DBP] higher than 115 mm Hg, or both
