Premature beating is a western medicine symptom, which belongs to the category of “palpitation” in Chinese medicine. Palpitation is divided into physiological and pathological, and pathological palpitation is divided into organic and non-organic. When Chinese medicine treats palpitation, it can only relieve part of the symptoms of organic lesions but not cure them. For non-organic disease, Yin Qiao San and Gui Spleen Tang can be used, but the identification of medication needs to consult a professional physician. The cause of palpitation is divided into deficiency and real, the deficiency is mainly due to deficiency of qi, blood, yin and yang, and the heart is not nourished (the heart is not nourished); the real is mainly due to external evils, phlegm and fire, or due to emotions. 1. Gui Shen Tang has the effects of tonifying Qi and blood, nourishing the heart and tranquilizing the mind (stabilizing the mind by nourishing the heart). It is mostly used in deficiency cases of deficiency of Qi and Blood. Note that it should be used with caution for people with fever and cold. 2. Yin Qiao San has the efficacy of dispersing wind, clearing heat and tranquilizing the heart. It is mostly used for the solid evidence of wind-heat disturbing the heart. Note that it should not be taken with tonic herbs and should not be used with caution for people with spleen and stomach deficiency (spleen and stomach weakness and cold). Premature beats need to go to the hospital in time to consult a professional physician to identify the evidence and treatment, not self-medication.
