It is mainly used to treat mild to moderate atrial premature beats or ventricular premature beats and to improve arrhythmias to a certain extent. But relatively speaking, it is not a mainstream treatment for coronary heart disease, and can be used as an adjunctive medicine, and it is not recommended for long-term use. If a patient is diagnosed with coronary heart disease, it is recommended to take aspirin, statin and other evidence-based drugs, while heart-stabilizing granules, although they can be used for anti-arrhythmia, are not very effective and can only be used as an adjunct.
