Criteria for a positive exercise test in asymptomatic patients with aortic stenosis
Development of dyspnea, angina, or presyncope or syncope, which should lead to stopping of the test
A rise in systolic pressure during exercise of less than 20 mmHg; the test is stopped if the systolic pressure falls more than 10 mmHg with exercise
Inability to reach 80 percent of the predicted normal level of exercise tolerance
More than 2 mm horizontal or downsloping ST segment depression compared to baseline that cannot be attributed to other causes; the test is stopped if there is more than 5 mm ST segment depression
The development of complex ventricular arrhythmias, such as ventricular tachycardia or more than four ventricular premature beats in succession, which should lead to stopping of the test
