No matter what your circumstances are, no doctor should ever ever yell at you. That is not professional and unexceptable. You calmly tell him or her, to lower that voice as it causes more anxiety. I would not take a medication if you know for sure you are going to get a heart test. Do not allow anyone to speak in a negative way to you. I am not sure I would not walk out. We have a hard enough time as it is without that kind of behavior. You did what your doctor said to do. I will keep you in my prayers, and hope there is a calm understanding so they can help you. ginnie
