Atrial fibrillation (Afib) and atrial flutter are common types of abnormal heart rhythms (arrhythmias) which affect the upper chambers (atria) of the heart. In atrial flutter, the heart beats too fast, but mostly continues to contract in a regular rhythm. AFib is a closely related condition in which the atria ...Atrial fibrillation also may impair cardiac output; loss of atrial contraction can lower cardiac output at normal heart rate by about 10%. Such a decrease is usually well tolerated except when the ventricular rate becomes too fast (eg, > 140 beats/minute), or when patients have borderline or low cardiac output to begin with.Atrial flutter is an arrhythmia that causes your heart to beat much faster than it should (around 300 beats per minute instead of the usual 60 to 100). Some people with atrial fibrillation have atrial flutter. If this is the case, you may get periods of atrial flutter followed by periods of atrial fibrillation.
