I had a stress test on the treadmill and the only thing I was wondering about was the time spent in. I only walked for six minutes and 37 seconds I believe when I was expecting a good 20 minutes. That was the only question I had but the nurses said everything was fine based on my time because it was based on my age.  I just felt like I hadn't even worked too hard went on the treadmill for that short amount of time.
