As others said, stress can play a big role of raising BP and heart rate. I don't think though that it would be elevated all of the time, all day long though because of that. Usually you will have short bouts of stress that will cause release of sympathetic hormones like norepinephrine etc, and that causes the effect. It can be quite abrupt too. I suppose if you have chronic stress then your corticosteroids would be elevated and those could raise it much of the day. I think you would have other symptoms too if your stress is that high, like anxiety and trouble sleeping etc.
Just a bit over 1 week ago I got stressed out doing a task at home and ended up causing tachycardia that resulted in my defibrillator having to go off. I have had other instances too of stress causing it. It really is a true phenomenon.
Try lowering your test dose for a few weeks and see if that helps, like the guy above suggested.
