Is atrial fibrillation genetic? It can be.
Atrial fibrillation, also known as AFib, can happen to anyone. Atrial fibrillation is the most common heart irregularity, or cardiac arrhythmia. More than 2.5 million Americans have atrial fibrillation.
Having relatives with AFib can increase your chances of being diagnosed. Atrial fibrillation that is inherited is called familial atrial fibrillation.
Recent studies suggest that up to 30 percent of people living with AFib have a relative with the condition.
