Symptoms Of Hypocalcemia

A Slow Heartbeat

As with skeletal muscle contractions, calcium is necessary for cardiac muscle to function, as it helps control the rhythm and heart rate. A typical human heartbeat ranges from sixty to one hundred beats per minute, and a slow heartbeat, called bradycardia, is defined as less than sixty beats per minute. A slow heartbeat means less blood and oxygen are flowing through the body, especially to the brain. A patient with bradycardia may feel lightheaded, short of breath, chest pain, and fatigue. However, note bradycardia is a normal condition for those who are very fit, and they do not suffer the same ramifications as someone suffering from hypocalcemia.
