Excessive sodium: High urinary levels of sodium result in increased levels of calcium. Certain defects in the kidney tubules transport system, which cause imbalances in sodium and phosphate, can lead to high calcium levels in the urine. A diet high in salt can also produce this effect.

Cardiac output, is a term used in cardiac physiology that describes the volume of blood being pumped by the heart, in particular by the left or right ventricle, per unit time. Cardiac output is the product of the heart rate, which is the number of heart beats per minute, and the stroke volume, which is the volume of blood pumped from the ventricle per beat; thus, CO = HR Ã SV. Cardiac output values can be represented using many physical units, such as dm3/min, but is usually denoted as L ...
