4. Fainting
Some organs in our body are more sensitive than others to a deficient supply of blood. Blood is necessary for all organs and tissues, but some of them can last for longer without enough irrigation. One of the organs in our body which is most sensitive to an insufficient supply of blood is our brain. Our brain burns many calories and requires a constant input of nutrients and other chemicals in order to function, and if the brain starts to fail because it doesn’t get the input that it needs in real-time, all the other organs and tissues will suffer because the brain commands them all.
A disturbed heart rate can impact the amount of blood that goes up to our head, and if the input is deficient our brain will go into an energy-saving mode in order to protect our basic functions. For that reason, people with Long QT syndrome might faint.
