Atrial fibrillation (AFib) is a prevalent heart condition characterized by an irregular heartbeat, which can lead to significant health risks if untreated. Dr. Jeremy London, a seasoned cardiothoracic surgeon, emphasizes that AFib can lead to blood pooling and clot formation, increasing the risk of stroke. Additionally, prolonged irregular heartbeats can weaken the heart muscle, potentially causing heart failure. Treatment options for AFib include medical therapy, which involves medications to control heart rhythm and reduce stroke risk; cardioversion, a quick procedure that resets the heart's rhythm using electric shocks; and ablation, a catheter-based approach that targets and neutralizes the triggers of AFib. Dr. London advises patients diagnosed with AFib to consult with their cardiologist to determine the most suitable treatment based on individual health conditions and symptoms.
