According to the CDC, approximately 2%of people younger than 65 years old and 9%of people 65 and older have AFib. Irregularities in heart rhythm become more common as people get older. Some individuals with AFib don’t experience any symptoms. Others experience symptoms that could include rapid heartbeat, palpitations, fatigue, or shortness of breath.

AFib can be managed with a doctor’s care and medication, and early diagnosis and treatment can prevent such complications.
