Atrial Fibrillation and Atrial Flutter
Defined as an “abnormal heart rhythm,” atrial fibrillation (AFib) and atrial flutter (Aflutter) afflicts approximately 2.7 million Americans. Caused by the upper chamber of the heart beating irregularly, AFib or AFlutter itself is not actually dangerous. The resulting side effects can be life-threatening, though. They are one of the leading causes of stroke; if left undiagnosed and untreated, AFib and Aflutter can cause blood clots, strokes, heart failure and heart problems.
