Can you have a normal echocardiogram and an abnormal stress test?

In clinical practice, exercise ECG is combined with stress Echo imaging for the evaluation of coronary artery disease. Although it is not uncommon for patients to have discordant results (abnormal ECGs and normal Echos), it was previously unclear whether this had any prognostic significance for these patients.

How long does the average person last on a treadmill stress test?

The test ends after maintaining your target heart rate long enough to capture readings about heart function, usually about 10 to 15 minutes. Your target heart rate is higher than when at rest and based on your age and fitness level. Technicians may end the test early if you experience severe symptoms or ask to stop.
