Usually the atria and ventricles work together so the heart pumps blood in steady rhythm. But in AFib, they don’t. The irregular beats can cause a fast, fluttering heart rate 100-175 beats per minute instead of the normal 60-100 beats per minute.
Atrial fibrillation is a condition that disrupts your heartbeat. A glitch in the heart’s electrical system makes its upper chambers (the atria) beat so fast they quiver, or fibrillate. This causes the lower chambers (the ventricles) to beat out of sync.
AFib can be dangerous because it raises your risk of stroke and heart failure.
The way to confirm AFib is with an ECG. The machine detects and records the electrical activity of your heart, so your doctor can see problems with its rhythm. You can do it in the doctor’s office, or you may need to wear a device that keeps track of your heart’s activity for a longer time to catch an episode. The device can be worn from 24 hours to 2 weeks, and sometimes longer.
