Atrial Fibrillation

Fibrilación auricular

What it means

Atrial fibrillation, also known as AFib or AF, is one of the most common types of arrhythmia, a problem with the rate or rhythm of the heartbeat. In AFib the heart beats irregularly and sometimes much faster than normal, and its upper and lower chambers do not work together as they should. The upper chambers (atria) contract in a chaotic manner, described as quivering. Symptoms can include extreme fatigue, heart palpitations, trouble breathing, chest pain, and dizziness or fainting, though some people have no symptoms. AFib may happen in brief episodes or be a permanent condition, and it can put a person at risk for stroke. Chest pain or signs of a stroke need urgent care; in the U.S., call 911.

Other Spanish termsWhere it is usedNote

MedlinePlus en español calls the condition fibrilación auricular and abbreviates it FA; its encyclopedia article lists FA among the alternative names. The noun is feminine (la fibrilación auricular), so a pronoun that refers to it is feminine too, as in the MedlinePlus sentence about people who do not know que la tienen. The aurículas are the upper chambers of the heart; the encyclopedia says that in FA they contract in a chaotic way or "tremble" (tiemblan).

Words that MedlinePlus en español uses with the term include arritmia (arrhythmia), palpitaciones cardiacas (heart palpitations), accidente cerebrovascular (stroke), medicamentos anticoagulantes (blood thinner medicines), cardioversión eléctrica and ablación con catéter (two procedures) and marcapasos (pacemaker). The closely related rhythm problem that English calls atrial flutter is aleteo auricular, and the topic page gives fibriloaleteo auricular under "Otros nombres".

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
