Technicians are not supposed to report any results. It requires a physician trained and skilled in reading them to do that, so that is why he didn't tell you. He may just have been trying to be helpful with his comment. There are several different types of stress tests, so keeping track of what you had is a good idea. If you go to another doctor or the Emergency Room with problems that seem related to your heart, it would be valuable information to know what tests you've already had and their results. This way some potential conditions could be ruled out without further testing, and studies for the correct diagnosis properly initiated. I think you are being a little "paranoid" as a result of the technician's response. As far as your normal work and exercise, if the doctor ordering the tests didn't say anything, you are most likely fine to pursue your regular activities. You can always check with him or her to be absolutely sure. Hope this helps.
