The problems with your heartbeat and your heart rate affect the way blood flows through your body, because the heart may have less effective strength. Insufficient communication between all four chambers of your heart can affect the rhythm and the coordination of your heart cells, and if they don’t beat all together and synchronized, the lower half of your heart – known as your ventricles – can malfunction.
A lack of potency and efficiency will harm your blood circulation, mostly decreasing the flow and reducing the oxygen and glucose input of cells. If your brain doesn’t get enough blood, it will have serious performance problems because your brain cells need a constant supply in order to work properly. Without enough blood input, your mental and neurological functions can decrease, and the first and most usual symptom of this is a feeling of dizziness. If the blood supply gets affected, even more, you can faint.
