𝗔𝘁𝗿𝗶𝗮𝗹 𝗳𝗶𝗯𝗿𝗶𝗹𝗹𝗮𝘁𝗶𝗼𝗻 is common heart rhythm disorder in which the electrical signals in the heart’s upper chambers (atria) become irregular and rapid. Atrial fibrillation causes the atria to quiver irregularly and stop contracting normally, leading to inefficient blood flow and increased risk of clot formation, especially in the left atrial appendage, which can lead to stroke. Patients often have symptoms such as palpitations, chest pain, shortness of breath, dizziness, fatigue, and decreased exercise tolerance. Atrial fibrillation can be intermittent (paroxysmal), persistent (lasting more than a week), or permanent. Treatment typically includes medications, and in some cases procedures such as catheter ablation, to control heart rate and rhythm, as well as anticoagulants to reduce the risk of stroke.
