Dizziness
Our brain needs an adequate and continuous supply of oxygenated blood to function properly. Still, in the case of atrial fibrillation patients, the supply of oxygen-rich blood stops, which results in dizziness. A person suffering from atrial fibrillation experiences the sensations of instability and faint when there is a lesser supply of oxygen in the blood. Dizziness refers to the creation of feelings that make you a falsely sense that your surroundings or you are moving, and this can happen very often in the case of atrial fibrillation. The irregularity in the heart rate, which is usually higher than 100 beats per minute, causes weakness and makes the person feel dizzy. The poor circulation of blood due to abnormal heart rate sometimes makes the patient pass out.
