Atrial Fibrillation (also known as AFib)

Under normal circumstances, the human heart pumps to a strong and steady beat – in fact, more than 100,000 heartbeats each day!

But if you have atrial fibrillation, or AFib, the heart doesn’t always beat or keep pace the way it should. Many people with AFib say they can feel their heart racing, fluttering or skipping beats.

AFib is the most common heart rhythm disorder (called an arrhythmia).

A major concern with AFib is that it allows blood clots to form in the heart. These clots can then travel throughout the body and block blood flow. This can cause strokes or injury to other organs. In fact, people with this condition are 5 times more likely to have a stroke than people without the condition. AFib can also lead to heart failure.

Finding and treating AFib early on can help you avoid these problems. In fact, new guidelines recommend early rhythm control to prevent the disease from getting worse. We also know certain conditions or behaviors can make AFib more likely. Taking steps try to address these may help to prevent AFib and other heart issues.
