Calcium is the most abundant mineral found in bone. Only a small percentage of total body calcium is found in blood. Blood calcium plays a major role in the regulation of heart rate and rhythm, because it is involved in the generation and transmission of current from the pacemakers to the heart muscle. Low blood calcium increases the risk for ventricular tachycardia, or too rapid contractions of the lower chambers of the heart.
