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.
A heart rhythm that's too slow can cause insufficient blood flow to the brain with symptoms such as: 1  Fatigue or feeling tired or weak. 2  Dizziness or lightheadedness. 3  Confusion. 4  Fainting or near-fainting spells. 5  Some people may feel short of breathe. 6  Feeling like it's hard to exercise. 7  In extreme cases, cardiac arrest may occur.
