Whenever a blood pressure cuff goes on my arm and tightens my heart begins to beat rapidly and my breathing becomes rapid and shallow and I feel uneasy. I do not go around 24 hours a day with rapid heartbeat an these other sensations. Have you ever heard of this before? What can I do? I want to have a breast biopsy but it can't be done when my blood pressure is high. For the last week and a half I have been taking a beta blocker Metoprolol and Hydrochlorothiazide that a physician's assistant prescribed. I have had an EKG as well as blood and urine tests which are all normal.
