Premature beats belong to the category of palpitations in Chinese medicine, i.e. palpitations in the heart. Chinese medicine practitioners treat palpitations according to the identification and typing of palpitations, such as heart fire, heart yin deficiency, phlegm fire disturbing the heart, heartburn and qi deficiency, qi stagnation and blood stasis, and water-drinking internal stagnation. The overall effect of Astragalus in the treatment of premature beats is not obvious, and it is not applicable without differentiation. Because astragalus has the effect of replenishing qi, it is effective for premature beats caused by heart qi deficiency, while qi surplus is fire, so astragalus is ineffective for premature beats caused by heart fire. The Chinese medicine treatment of premature beats emphasizes on the identification of symptoms, and it is better to use the right medicine, otherwise it is more likely to be counterproductive.
