An irregular heartbeat or “arrhythmia” is an abnormal heart rhythm, caused by problems with the heart’s electrical conduction system. Arrhythmia occurs when the heart beats too fast (tachycardia), too slow (bradycardia) or with a skipping rhythm. Arrhythmias can be caused by a heart attack or other (organic) damage to the heart muscle. The most frequent cause of arrhythmia, however, is a chronic deficiency of micronutrients in the billions of heart muscle cells. If this deficiency comprises the specialized “electrical” heart muscle cells that either generate (e.g. sinus node) or conduct the electrical impulse for the heartbeat, they no longer function properly and arrhythmia occurs.
