In recent years, with the rapid development of social economy and multiple changes in people’s lifestyle, the incidence of “tachyarrhythmia” has been increasing in different ages. However, because the mechanism is not completely clear, the clinical treatment effect is not satisfactory, and it brings great pain to patients, so how to prevent and treat it is an important problem to be solved. Through the clinical case observation, we found that some patients are triggered by “sympathetic excitation folding and arrhythmia” as an important basis, and proposed that “sympathetic nerve growth can directly affect the ventricular tissue remodeling and electrical remodeling”. However, the disadvantages of these drugs are not only the adverse effects, but also the limitations and negative frequency effects. According to TCM, emotional and mental factors (work stress, mental tension, panic and anxiety, irregular diet and life, etc.) lead to imbalance of yin and yang in the body, which is the main cause of arrhythmia, and treatment should be important to dredge the liver, calm the pulse and fix palpitations. The application of Chinese herbal formulas in combination can regulate many aspects to achieve the balance of yin and yang in the body, and it is deduced from modern medical theory that Chinese herbal medicine can reduce myocardial oxygen consumption, improve the tolerance of myocardium to blood oxygen to prolong myocardial survival time, adjust the imbalance of cardiac conduction and the nutritional supply of myocardial cells to calm the mind and relieve anxiety, without toxic effects and dependence, suitable for young and middle-aged people suffering from rapid ” arrhythmia “. Arrhythmia” patients. It can also improve depression in the elderly.
