Dizziness
An arrhythmia results in a lack of oxygen in your brain. This condition would usually make you experience lightheadedness or dizziness to the degree of passing out or losing balance. Some forms of arrhythmias associated with this condition include bradycardia and atrial fibrillation. While dizziness in atrial fibrillation is mainly triggered by irregular heartbeats, bradycardia causes lightheadedness by slowing your heartbeats. In extreme cases, both issues could lead to extreme fainting, dizziness, and fatigue. [3]
