Atrial fibrillation (or AFib) is a type of heart arrhythmia, or abnormal or irregular heartbeat. Some people describe atrial fibrillation as a quivering heart because it feels like your heart is fluttering in your chest.
If you think you have signs of atrial fibrillation in Las Vegas or Henderson, NV, Find a Doctor or call (702) 616-4900 to receive care at Dignity Health-St. Rose Dominican hospitals.
Not everyone with AFib experiences symptoms. In fact, you may not even realize you have AFib until your doctor discovers it during a physical exam.

If those treatments can’t restore your normal heart rhythm, there may be medicines to help manage your AFib. Consult with a cardiologist or surgeon to discover your ideal treatment option.
