Aortic regurgitation is mainly characterized by insufficient blood supply to the brain, overloading of the heart, and damage to the arterial valve. Symptoms are mainly dizziness, cyanosis, palpitation and thrombosis. 1. Since the blood going up to the brain is reduced after aortic valve regurgitation, the blood supply to the brain is insufficient, which is manifested as dizziness, cyanosis and other symptoms. 2. As the regurgitated blood enters the left ventricle, it can increase the preload of the left ventricle, and myocardial cells may undergo abnormal electrical activity due to the overload, which may be manifested as symptoms such as palpitations. 3. In case of arterial valve injury, thrombus may form in the blood due to the activation of the coagulation system and its repeated action. To summarize, patients are advised to make judgments and treatments under the doctor’s advice by combining their own conditions and examination results.
