I also have Baroreflex failure that has been diagnosed by a cardiologist and Electrophysiologist. I researched this diagnosis May 2023. I had bilateral Thyroid cancer in 2001 and 2008, total thyroidectomy . Brain stem stroke in 2017. My bp started surging
in 2022 because of severe personal stress and severe surges again in 2024 because of personal stress. My bp has severely flucuated since then. I'm very sensitive to medications that I've taken in the past. All I can tolerate is Atenolol 25mg that are split in half , because this bp medication isn't time released. I take Atenolol 12.5 mg as needed on a daily basis to somewhat help my bp come down. Bp fluctuates from one hour to the next or several hours later, I have to monitor bp a lot during every 24 hours.
