Can low vitamin B12 cause irregular heart beat?

No. B12 is involved in blood cell formation and nervous system function. Its deficiency can result in macrocytic (large blood cell size), and a host of neurological and GI symptoms. Some feel stamina and energy level might be affected. No connection to irregular heartbeat.
No. B-12 deficiency by itself would not be expected to cause an irregular heart rate. B-12 deficiency results in anemia, which may result in a faster heart rate, and increased catecholamines (such as adrenaline). I suppose the increased adrenaline could make one more likely to have pvcs. This is not a major reported problem associated with b-12 deficiency. Neuropathy would be much more concerning.

Is it safe to take b complex vitamin and a hair skin And nail vitamins with lupus and irregular heart beat?

Yes, perfectly safe. The only vitamins that can be toxic are Vitamins A, D, E and B6. One has to take massive doses of A, D & E to become toxic. One should avoid more than 250 mg a day of B6 but the combined amount in your vits is likely well below that. I advise those with irregular heartbeats to take at 250-400 mg/day of Magnesium Taurate; your vits probably have little magnesium. Hawthorne extract may also help. Read more...

Usually 3.3 or lower. This depends on other health issues. Other electrolyte disorders that are present might make a person more sensitive to low potassium.
