I am new here. I haven't been diagnosed, but i have been cleared of everything imaginable. I suspect i may have some type of dysautonomia. My heart rate jumps with standing, walking, and eating. I have a few questions: 1. I seem to understand that your heart rate goes up due to blood pooling or a drop in blood pressure. If you take beta blockers to slow the heart rate, then doesn't that result in insufficient blood flow? 2. What can I do to help my situation until I get a diagnosis? What should i eat and drink? 3. I know some say they do not have blood pressure changes. If you do have blood pressure changes, does that mean your case is worse?
