Abnormal Heartbeat
It’s a common misconception that carbon dioxide is solely an undesirable waste product of human metabolism. In reality, carbon dioxide serves many critical physiological functions within the body, one of which is regulating blood pH. When the concentration of carbon dioxide in the blood decreases, it increases blood pH or respiratory alkalosis. This can cause various symptoms, including an abnormal heart rate.
The relationship between low carbon dioxide in the bloodstream or hypocapnia and abnormal heart rate is complicated and needs to be fully understood. However, there are a few potential mechanisms by which low carbon dioxide levels could lead to an abnormal heart rate.
One possibility is that low carbon dioxide levels stimulate the release of epinephrine, a hormone that speeds up the heart rate. Another possibility is that respiratory alkalosis interferes with electrical conduction in the heart, leading to arrhythmias.
Whatever the mechanism, it’s well-established that hypocapnia can cause an abnormal heart rate. For individuals experiencing irregular heartbeat or other strange symptoms, it’s essential to see a doctor to rule out any underlying medical conditions.
