I am b12 deficient (level 192) (MMA 28). I have an unusually high pulse, goes up to 130, even when I am resting. I have been through a CT-scan of my heart, been observated in the hospital overnight, blood tests taken - all looks fine. (I´m 39 years old by the way, and have never had heart problems before)
My Doctor says, that a high pulse/heart palpitations is not a sign of B12 deficiency, unless you are anemic - which I´m not, my hemoglobin is fine. So he thinks that I must have a heart problem after all, that they just didn't pick up in the hospital.
What is your experience, have you had high pulse without being anemic?
