Symptom #2: Fast Heart Rate
Once oxygen has been inhaled into the lungs and absorbed into the blood, it then needs to be circulated around the body. This is the job of the heart, which acts as a pump to circulate the blood around the body’s system of blood vessels. The faster the heart pumps, the more blood is circulated.
If there is not enough blood in the body then the heart may be expected to increase its work rate to compensate. This means increasing the rate at which it pumps. With more oxygen-rich blood circulating through the body, there should hopefully be enough to meet the demand.
