Symptoms
Overview. Atrial fibrillation (A-fib) is an irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots in the heart. A-fib increases the risk of stroke, heart failure and other heart-related complications.. During atrial fibrillation, the heart's upper chambers (the atria) beat chaotically and irregularly — out of sync with the lower chambers (the ventricles) of ...
Fibrilación Auricular
Causas. Para comprender las causas de la fibrilación auricular, puede resultar útil saber cómo late normalmente el corazón.. El corazón común tiene cuatro cavidades: dos superiores (aurículas) y dos inferiores (ventrículos). Dentro de la cavidad superior cardíaca derecha (aurícula derecha), hay un grupo de células llamado "nódulo sinusal".

Afib stands for atrial fibrillation (AF), which is a type of arrhythmia, or abnormal heartbeat. Afib is caused by extremely fast and irregular beats from the upper chambers of the…

There are three types of atrial fibrillation: 1. Paroxysmal Afib:This type of Afib occurs intermittently and stops on its own within seven days. 2. Persistent Afib: This type of atrial fibrillation lasts longer than seven days. Unlike paroxysmal Afib, it may require cardioversion(electric shocks to the heart) to restore normal rhythm. 3. Long-stand...

Sometimes Afib causes no symptoms at all; you might not know you have it. When it does cause symptoms, those can include: 1. Angina(chest pain caused by a reduced blood supply to the heart muscle) 2. Dizziness 3. Fainting (syncope) 4. Fatigue 5. Palpitations (feeling like the heart is fluttering or racing) 6. Weakness 7. Shortness of breath Afib ca...

Afib occurs more often in people with certain characteristics: 1. Age older than 50 years 2. Alcohol use 3. Heart failure 4. High levels of stress 5. High blood pressure 6. Male gender 7. Obesity 8. Sleep apneaor poor sleep 9. Tall height 10. Thyroid disease The condition can run in families, especially when it happens at a young age.

Some cases of Afib involve atrial fibrillation with rapid ventricular response (RVR). This is when the rapid contractions of the atria make the ventricles beat too quickly. If the ventricles beat too fast, they can’t receive enough blood. So they can’t meet the body’s need for oxygenated blood. This can lead to heart failure.
