Bradycardia can be treated with traditional Chinese medicine. Shen Song Yangxin Capsule was developed under the guidance of collateral disease theory of traditional Chinese medicine, which changed the clinical treatment of arrhythmia from "antiarrhythmic" to "regulating heart rhythm". It plays a therapeutic role by regulating the function of the heart, so it can be treated quickly and slowly. Evidence-based medicine research shows that Shen Song Yangxin Capsule is effective in treating bradyarrhythmia, which can increase ventricular rate by 7.65438 0.05 beats/min.
