During an atrial fibrillation episode, the two upper chambers (known as the atria) beat irregularly due to a faulty misfiring of the electrical signals within the atria. This results in an irregular heartbeat. An atrial flutter is a faster heartbeat, although it is still regular. The atrial flutter means the atria are beating faster than the ventricles, which are the lower chambers of the heart. It’s also possible to experience an atrial flutter and atrial fibrillation simultaneously.
It’s important to consult your physician if you are concerned about atrial fibrillation or other heart conditions. The providers at Mass General Brigham can create a customized treatment plan for you to treat AFib and other heart conditions.
