3. Bradycardia
Bradychardia is the technical term that refers to a heart rate that is lower than normal. In other words, the heart of people with bradychardia beats less time per minute than it should. Since our heart pumps blood to our body, and insufficient heart rate might have catastrophic consequences in all our vital functions. If our heart doesn’t beat as fast as it should, the blood won’t reach our cells in due time, and the supply of nutrients, water, and oxygen will not be enough for them.
As a result, people with bradychardia often feel fatigued, dizzy, and too weak to perform their daily tasks. In more severe cases, a heart rate that is too low might mean that our brain isn’t getting as much blood as it should, and when that happens, it immediately starts shutting down to save energy for our vital functions, and we faint.
