Atrial Fibrillation Symptoms: What You Need to Know

Atrial fibrillation, commonly known as AFib, is a type of irregular heartbeat that can cause a variety of symptoms. One of the most common signs experienced by patients is palpitations. During an AFib episode, the heart's atria lose their ability to contract effectively, leading to an irregular and often rapid heartbeat. This abnormal rhythm can make individuals feel as though their heart is racing or fluttering.

Common Symptoms of Atrial Fibrillation

In addition to heart palpitations, people with AFib may experience other symptoms such as fatigue, shortness of breath, and dizziness. These sensations occur due to the heart's reduced efficiency in pumping blood throughout the body. For patients who also suffer from coronary artery disease, AFib can trigger angina, fainting, or even lead to more severe complications like heart failure or shock.

Complications Associated with AFib

Heart Failure: When AFib persists, it can weaken the heart over time, potentially leading to heart failure. This condition arises when the heart cannot pump enough blood to meet the body's needs.

Acute Pulmonary Edema: In patients with rheumatic heart disease and mitral valve stenosis, AFib can precipitate acute pulmonary edema. This condition causes fluid buildup in the lungs, making it difficult to breathe and sometimes resulting in coughing or even coughing up blood.

When to Seek Medical Help

If you experience sudden or severe symptoms such as chest pain, difficulty breathing, or fainting, it's crucial to seek immediate medical attention. Early diagnosis and treatment of AFib can significantly reduce the risk of complications and improve overall quality of life.
