What is the main cause of AFib?
Atrial fibrillation is most often caused by changes to the heart's tissue or the electrical signaling that helps the heartbeat.
Is AFib life threatening?
AFib itself usually isn't life-threatening. But it's a serious medical condition that needs proper treatment to prevent stroke. Treatment for atrial fibrillation may include medicines, therapy to shock the heart back to a regular rhythm and procedures to block faulty heart signals.

AFib may be brief, with symptoms that come and go. An AFib episode may resolve on its own or it may be persistent and require treatment. Sometimes AFib is permanent, and medicines or other treatments can't restore a normal heart rhythm.
