Serious Signs Anemic Individuals Often Exhibit

Unusually Fast Heartbeat

An unusually fast heartbeat (tachycardia) is a common manifestation in anemic individuals. Anemia occurs when an individual's body does not have enough healthy red blood cells to carry out their function of oxygen delivery. Because anemia causes the blood to have an inadequate oxygen concentration, the tissues around the body do not receive the amount of oxygen they need. In order to carry out their specialized cellular functions that make organs work, the cells require cellular energy or ATP. Adequate amounts of ATP can only be produced when enough oxygen is delivered to the cell.

The brain of an anemia patient can detect there is not enough cellular energy, and sends signals to the heart to compensate for the poor oxygen concentration of the blood. The heart then begins to beat faster and harder in an attempt to pump oxygen-poor blood into the lungs and back out to the tissues around the body quicker and more effectively. Tachycardia caused by anemia is a symptom that does not typically occur intermittently. Therefore, a consistent elevated baseline heart rate at rest can indicate the presence of anemia.
