When used as a prognostic factor for the development of ventricular tachycardia, they have a sensitivity of 72% and a specificity of 75%, yielding a positive predictive value of 20% and a negative predictive value of 20%.
Stress and potential cardiac damage from exercise during the test is a problem in patients with ECG abnormalities at rest or in patients with severe motor disability. Pharmacological stimulation from vasodilators such as dipyridamole or adenosine, or positive chronotropic agents such as dobutamine can be used.
