Mild atrial fibrillation requires a decision on the need to initiate anticoagulation based on the atrial fibrillation stroke score. Specific measures are recommended under medical supervision. If the score is ≥2, oral anticoagulant therapy (e.g., warfarin) is recommended; for a score of 1, warfarin or aspirin anticoagulation may be chosen, but oral anticoagulant therapy is recommended; for a score of 0, aspirin may be chosen or no antithrombotic therapy may be used and no anticoagulant therapy is recommended. In addition to general treatment, regular review is recommended to monitor the progress of the disease and avoid deterioration. Clinical symptoms such as panic, palpitations (rapid heartbeat, often accompanied by panic), shortness of breath, fatigue, irritability, etc. need to be seen as soon as possible to receive standardized treatment. Specific diagnosis and treatment should follow the doctor’s instructions.
