Atrial fibrillation is a condition that causes many symptoms. The fluttering in your chest might seem non-serious at first, but it can develop into a serious condition. It is always best to visit a heart specialist and receive a proper diagnosis as well as treatment. If you have this condition, you might have seen fainting as a symptom and wonder: can you pass out from AFib? Carry on Reading to learn!

Reasons Behind Syncope From Atrial Fibrillation

There are three common reasons that result in fainting due to AFib, and your heart specialist can determine what is causing you to pass out. Here is more on how you can pass out from AFib:

1. Your Heart Rate is Going Too Fast

Atrial Fibrillation is a condition that can result in rapid heart rate, and it could be 170, 180, or even faster. When your heart rate is fast, it causes poor circulation to your brain, which can result in fainting. While usually, symptoms like dizziness, chest pain, and shortness of breath take place, you might pass out due to increased heart rate. Generally, older patients with existing cardiovascular conditions might pass out due to AFib.

2. Your Heart Rate is Going Too Slow

Sometimes, the ventricle pauses with atrial fibrillation. When you have atrial fibrillation, the upper chamber of your heart (atrium) is going very fast, up to 300 to 600 beats a minute. The lower chamber of the heart or the ventricle is responsible for the pulse, and it can slow down or pause even if you are in atrial fibrillation. In simple terms, the heart rate and pulse may pause for a few seconds, which leads to dizziness, lightheadedness, and even fainting. So, a slow heart rate can be the reason you pass out from AFib.

3. You Are Having an Episode of Conversion Pause

You might pass out from AFib due to a conversion pause — when your AFib episode actually stops, it takes several seconds for your actual heartbeat to kick in. It is almost as if your natural heartbeat is too exhausted from being in atrial fibrillation to start again. While your heart is getting ready for a natural heartbeat to resume, your heart is in a conversion pause. As a result, you might pass out due to the AFib ending and the natural heartbeat taking time to kick start.

Final Takeaway

Atrial Fibrillation brings forth many symptoms, and fainting is among the indications you might experience. You might pass out from atrial fibrillation if your heartbeat is too fast, too slow, or due to a conversion pause. Your cardiologist can assess your condition to determine what is the most suitable treatment. Also known as syncope, fainting due to AFib might be a sign of severity.
