What happens when you have atrial fibrillation (AFib)?

ANSWER

The faulty signals start in your heart's two upper chambers, called atria. Sometimes, though, it can also affect the two bottom chambers, called ventricles. When that happens, your doctor will tell you that you've got a specific type of atrial fibrillation called AFib with rapid ventricular response. It makes your heart beat too fast.

That can make you feel tired or short of breath. It can also lead to a stroke or heart failure, but the right treatment will bring your symptoms under control and get you back into a healthy rhythm.
