Atrial fibrillation is abbreviated as atrial fibrillation, which is characterized by extremely irregular pulse. According to statistics, there are more than 8 million patients with atrial fibrillation in my country, and 70% of them are elderly people between 65-85 years old. The reason why the elderly become a high incidence group of atrial fibrillation is on the one hand because the heart of the elderly is gradually degenerative, and on the other hand because the elderly often suffer from high blood pressure, diabetes, coronary heart disease and other diseases, these can be caused by Causes of atrial fibrillation. Atrial fibrillation can cause symptoms such as panic, dizziness, and shortness of breath, or aggravate the original heart disease, but its harm is still easy to cause stroke. Thrombosis is easy to form in the atrium of patients with atrial fibrillation. Thrombosis falls with the blood and runs to the brain. It is easy to block the cerebral blood vessel stenosis and block blood supply to the brain, resulting in stroke. The probability of stroke is about 4 to 7 times that of people with normal heart rhythm. The probability of atrial fibrillation is currently less than 1%. Therefore, patients with atrial fibrillation urgently need effective and safe treatment drugs. Songsong Yangxin Capsule with integrated adjustment advantages can adjust the multi-ion channels of myocardial cells, and can regulate the autonomic nerve function of the heart, improve the blood supply of myocardium, and improve myocardial fibrosis. The Chinese Academy of Medical Sciences Fuwai Cardiovascular Research found that Shensong Yangxin Capsule has a significant regulating effect on a variety of ion channels such as sodium, potassium and calcium in myocardial cells. The Heart Center of Beijing Chaoyang Hospital of Capital Medical University found in evidence-based medicine research that Shensong Yangxin Capsule significantly inhibits the occurrence and duration of paroxysmal atrial fibrillation by affecting multiple myocardial cell ion channels, and relieves symptoms such as palpitation, dizziness, and shortness of breath. , The efficacy is comparable to the western medicine Xinluoping, and no cardiac side effects of Shensong Yangxin Capsule have been found in the study. Elderly patients with atrial fibrillation taking Shensong Yangxin capsules can eliminate the hidden danger of stroke on the basis of effective treatment of atrial fibrillation.
