Atrial fibrillation, or AFib, is a common type of irregular heartbeat. It occurs when the electrical signals that control the rhythm of the heart become chaotic, causing the heart to beat irregularly. While AFib can be a sign of a weak heart, it does not necessarily mean that the heart is weakened.
What is Atrial Fibrillation (AFib)?
Atrial fibrillation is a term used to describe an irregular heart rhythm. It is caused by the electrical signals in the heart becoming chaotic and the heart beating irregularly. AFib is the most common type of arrhythmia, or irregular heartbeat, and affects millions of people around the world.
What Causes AFib?
There are many potential causes of AFib, including coronary artery disease, high blood pressure, and heart valve disease. Other potential causes include alcohol abuse, certain medications, and thyroid disorders. In some cases, the cause of AFib is unknown.
What Are the Symptoms of AFib?
The most common symptom of AFib is an irregular heartbeat, which can feel like a fluttering or racing sensation in the chest. Other symptoms may include shortness of breath, dizziness, fatigue, and chest pain.
Does AFib Mean You Have a Weak Heart?
AFib does not necessarily mean that a person has a weak heart. In some cases, AFib can be a sign of an underlying heart condition, such as coronary artery disease or heart valve disease. However, many people with AFib do not have any underlying heart conditions and their hearts are not necessarily weak.
It is important to talk to your doctor if you have any symptoms of AFib. Your doctor can help determine if you have a weak heart or any other underlying conditions that may be causing your AFib.
