Atrial fibrillation, commonly known as Afib, is a medical condition that affects the heart’s rhythm. It is characterized by an irregular and often rapid heartbeat that can lead to complications such as stroke, heart failure, and other heart-related problems. This article will explore the definition, meaning, and associations of Afib.
Definitions
Afib is a type of arrhythmia, which means that the heart beats irregularly. In Afib, the heart’s upper chambers, called the atria, quiver instead of contracting normally. This causes blood to pool in the atria, which can lead to the formation of blood clots. If a clot breaks loose, it can travel to the brain and cause a stroke.
Origin
The exact origin of Afib is unknown, but it is believed to be caused by a combination of genetic and environmental factors. Risk factors for Afib include high blood pressure, heart disease, obesity, diabetes, and sleep apnea.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, Afib is defined as “an irregular and rapid heartbeat that can increase the risk of stroke, heart failure, and other heart-related complications.” The Oxford English Dictionary defines Afib as “a condition in which the heart beats irregularly, often causing palpitations and shortness of breath.”
