May 15, 2024 · Atrial fibrillation, often called AFib or AF, is the most common type of treated heart arrhythmia. An arrhythmia is when the heart beats too slowly, too fast, or in an irregular way. When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular, and blood doesn't flow as well as it should from the ...
Nov 30, 2023 · In addition, new recommendations addressing atrial fibrillation and thromboembolic risk assessment, anticoagulation, left atrial appendage occlusion, atrial fibrillation catheter or surgical ablation, and risk factor modification and atrial fibrillation prevention have been developed.
Nov 30, 2022 · Atrial fibrillation, also known as A-fib or AF, is one of the most common types of arrhythmias (irregular heart rhythms). Atrial fibrillation causes your heart to beat irregularly and sometimes much faster than normal, and your heart’s upper and lower chambers do not work together as they should.
