Symptom 7: Fainting – The Abrupt Blackout
One moment you’re standing, the next you’re waking up from an abrupt, unexplained blackout. This sudden loss of consciousness, also known as syncope, is a symptom that might herald the presence of AFIB.
The feeling can be like a sudden curtain dropping over your consciousness, or it may come with a warning—perhaps a feeling of lightheadedness or a grayness creeping into your peripheral vision. Regardless, the experience is unnerving, to say the least.
The cause behind these fainting spells lies in the insufficient blood supply to the brain. In AFIB, the irregular heartbeat can cause the blood pressure to drop suddenly, momentarily depriving the brain of adequate blood, resulting in a blackout.
The suddenness of these spells makes them particularly distressing. You might be at the supermarket, at work, or even crossing the street, and suddenly, your world goes black. These abrupt blackouts not only interrupt daily life but also pose a significant safety concern.
While fainting can be caused by various issues, recurrent episodes should not be brushed off lightly. It’s essential to understand that a sudden, unexplained loss of consciousness could indicate a serious underlying heart condition, such as AFIB, and should be addressed promptly. (7)
