Dizziness or Lightheadedness
As we mentioned above, the brain is not exempt from being affected by arrhythmia. Therefore, it should not be surprising to learn that dizziness or light-headedness can also be a result of arrhythmias, especially atrial fibrillation (which is the result of very quick electrical activity of the atria) and bradycardia (which causes the opposite- a slowed heartbeat). If left untreated bradycardia can lead to fainting, dizziness, and extreme fatigue. In extreme cases, a loss of balance or passing out can occur. Believe it or not, it is a serious issue if the brain is not getting enough blood. More often than not it is suggested that individuals with bradycardia get a pacemaker implanted.
