4. Dizziness: A Spin on Perception
Dizziness, often described as a feeling of unsteadiness or a sensation that the room is spinning, is another symptom that could point to AFIB. This symptom occurs due to the irregular heartbeat of AFIB, resulting in a decreased blood flow to the brain. When the brain isn’t receiving enough blood, it can cause a range of symptoms, including dizziness, fainting, or lightheadedness.
Dizziness as a symptom of AFIB can come and go, much like the irregular heartbeat that causes it. You might have episodes of feeling unsteady or lightheaded that last for a few minutes or several hours.
These episodes can occur at any time, but they may be particularly noticeable when you stand up quickly or change position. They can also occur during an AFIB episode when the heart rate is especially fast or irregular.
The presence of dizziness can be an alarming symptom, as it can increase the risk of falls and injuries, particularly in older adults. Additionally, dizziness can be a particularly unsettling symptom, as it can impact your ability to perform daily activities and can lead to feelings of fear and uncertainty.
Like other symptoms of AFIB, dizziness is not exclusive to this condition and can be a sign of a variety of other health issues, including low blood pressure, certain neurological conditions, and anxiety disorders. However, if you’re experiencing unexplained dizziness, particularly if it’s accompanied by other symptoms like palpitations, shortness of breath, or fatigue, it’s essential to seek medical attention to rule out AFIB or other serious conditions.
Understanding how AFIB could be causing this dizziness is crucial. In AFIB, the rapid and irregular contractions of the heart’s upper chambers (atria) can cause the heart to pump blood ineffectively. This lack of efficiency can result in a reduction of blood flow to the brain, leading to sensations of dizziness, light-headedness, or even fainting in more severe cases. (4)
