Symptoms of Atrial Fibrillation

A heart arrhythmia is a blanket term given to irregular heartbeats. Atrial fibrillation, also known as Afib, is a type of arrhythmia. In this particular case, the heart is beating faster than it normally would. Patients with Afib also have a malfunction in how the upper and lower chambers of the heart are working. Under normal circumstances, both chambers work together to pump blood through the body.

When atrial fibrillation is present, the lower chambers cannot pump blood to the lungs properly or do not fill properly, and blood gathers in the heart. This type of arrhythmia can be present without a single symptom, or there can be several symptoms that occur as warning signs. There are three main types of A-fib. While symptoms are not type-specific, episode duration and treatment options are.

Common Symptoms

When noticeable symptoms occur, the most common one is described as a fluttery heartbeat. It is caused when the upper heart chambers quiver as a result of irregular electrical activity. Atrial fibrillation may also present a distinct rapid heartbeat, often noticed through feeling chest-thumping or increased chest pressure.
