B12 deficiency: Vitamin B12 deficiency can cause pernicious anemia which in turn can cause irregular heart beats.

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.
