[|Human|] I am having tests done on my heart as I have times I feel my heart racing. I have no results yet. I did find out my b12 is a little low. I have neen taking a daily b12 supplement for about 3 weeks This week I have not had any issues with my heart racing. Is it possible the b12 is helping?
[|AI|]  Hello! Welcome on Chat Doctor! I understand your concern and would explain that vitamin b12 deficiency is not directly related to the heart rate, but it may cause chronic anemia, which is one of the most common causes of heart palpitations. I would recommend performing some tests to exclude other possible causes of cardiac arrhythmia: -cardiac ultrasound and resting ECG to examine your cardiac function and structure-ambulatory 24-48 hours ECG monitoring to examine your heart rhythm trends during the day-blood tests (complete blood count, thyroid hormone levels, fasting glucose, blood electrolytes). Furthermore, I recommend continuing vitamin B12 supplements, as this vitamin is necessary for the normal function of many organs. Hope to have been helpful! Best wishes,
