4. Dizziness, fainting, and palpitations
Our hearts are the pumps that deliver oxygen through our blood to the body. When such supply is compromised, organs start to dysfunction. Such pumps act by a specific and regular rhythm through a pacemaker that is in our heart. On the other hand, the heart itself needs a constant oxygen supply through the coronary arteries, when this is not supplied efficiently, the heart’s pacemaker starts to dysfunction, and the heart rate begins to fluctuate. This fluctuation makes us feel our heartbeats, which doesn’t normally occur unless the rate or rhythm changes -as a good example, we may feel a pounding in the chest after climbing a long flight of stairs or running for a long distance- and this is called palpitations. Such irregularities of heart rate affect the blood supply to our brains, which are the most vulnerable of our organs to oxygen deprivation, thereby leading to dizziness and, in more severe cases, syncope or fainting.
