There are many different types of abnormal heart rhythm. What type you have depends on where in your heart the rhythm (electrical impulse) starts, and whether it causes your heart to beat too fast, or too slow. The most common abnormal rhythm is atrial fibrillation.
Not a Normal Heart Rhythm or Rate. 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.
