mitral valve prolapse
"I've had great luck with this product for the last ten years. I'm on an extremely low dose (12.5mg every 24 hours), and it controls my heart rate and blood pressure beautifully with no side effects. I have found if I take a whole 25mg. tablet a day, sometimes my feet seem a bit cold, but I'd much rather have a controlled heart rate and wear socks than a heart rate in the 120s and warm feet. Overall, though, this product has been fantastic for me!"
