Arrhythmias make cause your heart to beat too slow, too fast or irregularly. Some arrhythmias may be harmless while others may be more serious and require lifestyle changes and medical intervention.
Atrial fibrillation (commonly called AFIB or AF) is one of the most common types of abnormal heart rhythms. AFIB occurs when the two upper chambers of the heart (atria) beat chaotically and irregularly out of coordination with the lower chambers of the heart (ventricles). Common symptoms of AFIB are heart palpitations, shortness of breath and weakness. AFIB can increase your risk for heart failure, stroke and other heart conditions.
