Atrial fibrillation (AFib) is indeed a dangerous condition if left untreated. It causes the heart's upper chambers to beat irregularly and out of sync, which can lead to poor blood flow and an increased risk of serious health issues such as blood clots, stroke, heart failure, and other heart-related complications. Specifically, AFib can cause blood to pool in the heart, leading to clot formation that may travel to the brain and cause a stroke. It also increases strain on the heart, potentially leading to heart failure. However, AFib is manageable with early diagnosis and treatment, including medications and procedures like ablation therapy to restore normal heart rhythm. Immediate medical attention is advised if symptoms like chest pain, severe dizziness, or a rapid heart rate persist.
