Symptom 8: Fainting or Loss of Consciousness
An abrupt loss of consciousness or fainting, also known as syncope, can be a severe symptom of an AFIB stroke. When the brain doesn’t receive an adequate supply of oxygenated blood due to an irregular heart rhythm, it could lead to a sudden blackout. This sign warrants immediate medical attention.
Fainting might be accompanied by other symptoms such as dizziness or lightheadedness. It’s important to note that while fainting can occur due to various reasons like dehydration or standing up too quickly, in the context of AFIB, it could signify a more serious issue like a stroke.
The crucial aspect here is the suddenness and inexplicable nature of the fainting spell. If you or a loved one experiences a sudden loss of consciousness, especially if it’s accompanied by other symptoms on this list, it’s essential to seek immediate medical help. (7)
