Atrial fibrillation (AFib) is a common heart rhythm disorder that occurs when the electrical signals in the heart become irregular, leading to a chaotic heartbeat. This irregularity occurs specifically in the atria, the two upper chambers of the heart, which can result in a fast or fluttering heart rate. Symptoms may include palpitations, shortness of breath, fatigue, and dizziness, though some individuals may experience no symptoms at all. AFib increases the risk of stroke and other heart-related complications, making its management crucial.
The causes of atrial fibrillation can vary widely, including high blood pressure, heart valve issues, coronary artery disease, and even excessive alcohol consumption. Diagnosis typically involves an electrocardiogram (ECG), which can help determine the heart's rhythm and identify any irregular patterns. Treatment options range from lifestyle changes—like diet and exercise—to medications that control the heart rate or prevent blood clots, and in some cases, procedures such as ablation may be recommended. If you suspect you have AFib or are experiencing symptoms, consulting with a healthcare professional for an accurate diagnosis and tailored treatment plan is essential.
