4. Lightheadedness
Since the blood circulates throughout all our bodies, problems that affect the way it is pumped will have an impact on other functions that do not depend directly on the way our heart is beating. Other organs will have problems if the supply of blood isn’t constant or if it is not enough to carry the oxygen, the glucose and other nutrients that our cells need for their metabolism and other important functions; also, poor or deficient blood flow will slow down the rate at which toxic substances and metabolic waste loads are relieved from the tissues and eliminated from our body.
Poor supply of oxygen and glucose will affect our brain functions, and therefore, our mental state and our capacity to process information from our environment and keep a state of clear consciousness. For this reason, when ventricular tachycardia happens, we might feel light-headed or vertiginous as our brain struggles to process information.
