mitral valve prolapse
"I have Mitral Valve Prolapse and extreme anxiety where I basically depleted my adrenals from being so anxious all the time. I was in a constant state of fight or flight. Since my Dr. prescribed this medicine a few years ago it has worked wonders and changed my life. I am now able to function fairly normally as it greatly reduces my heart rate. I seem to have extreme sensitivity to heat as well and it calms my pulse in warm temperatures too. Its never fun to always be aware of a racing heart rate and this med really helps. Takes about 20 mins to kick in but then I usually feel much calmer. Very happy to been prescribed this."
