The heart rate may not be normal during accelerated breathing, and the heart rate is usually accelerated during accelerated breathing. There is a correlation between breathing and heart rate. Accelerated breathing, the heart rate can generally reach 100-150 times / min, some can even reach 180 times / min, usually occurs during exercise, exercise will consume a large amount of oxygen, the production of carbon dioxide, carbon dioxide in the lungs increased dramatically, so that the sympathetic nerves are excited, the role of adrenal glands, adrenal glands to release norepinephrine and epinephrine to act on the cardiovascular system, so that the cardiac output increases, the heart rate increases. It is a normal physiological phenomenon that the heart rate increases to provide sufficient oxygen to the body. Therefore, the body’s heart rate is not normal during accelerated breathing, and it will speed up to accommodate the body’s needs, and when breathing returns to a normal rate, the body’s heart rate will return to the normal range. If the breathing and heartbeat abnormalities do not subside, it is recommended to seek medical attention as soon as possible to avoid delaying the condition.
