Brain ischemia. Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.
Tachycardias also can cause serious injury to other organs. For example, the brain, kidneys, lungs or liver may be damaged during prolonged cardiac arrest. Blood clots can form in the heart's upper chambers because of atrial fibrillation, a disorder in which the atria quiver instead of beating effectively. Blood that isn't pumped completely out of the atria when the heart beats may pool and clot.
