Very courteous and helpful. I went for a stress test and they were quite reassuring. They made sure that they had the shot ready to counteract the side effects of the injection. I have to do the test medically instead of the treadmill because of my back and hip. They had oxygen and at the first sign of the side effects they immediately gave me the shot to counteract them and made sure that I didnt need the oxygen to catch my breath. It was a pretty good experience. I hate having the shot but of course thats not their fault....
