Myocarditis is equivalent to the category of “palpitation (rapid heartbeat, often accompanied by panic)” in Chinese medicine, and its tongue can be divided into heart deficiency and timidity, heart blood deficiency (insufficient blood in the heart), yin deficiency and fire (deficiency of yin and essence in the body, and the emergence of hyperactive deficiency and fire) and other different pathologies with different manifestations. In the case of heart deficiency and timidity, the tongue is thinly coated with white fur, accompanied by palpitations (rapid heartbeat, often accompanied by panic), restlessness, and fearfulness. If the heart is deficient in blood (insufficient blood in the heart), the tongue will be pale red, accompanied by palpitations (rapid heartbeat, often accompanied by panic), shortness of breath, and a colorless face. In cases of Yin deficiency and fire (deficiency of Yin essence in the body, resulting in hyperactive fire), the tongue is red with little fluid and little or no moss, accompanied by palpitations (rapid heartbeat, often accompanied by panic), easy to be frightened, and five heart-heat (heat in the heart of the hands and feet, and self-consciousness of the heart and chest (irritability and sultriness)). If the heart yang is not vibrant, the tongue is pale with white moss, accompanied by pale face and cold limbs (cold body). For those with water-drinking overriding the heart, the tongue is pale and fat, the moss is white and slippery, accompanied by palpitations (rapid heartbeat, often accompanied by panic), dizziness, and swelling of the lower limbs. For those with stasis obstructing the heart veins, the tongue is dark purple or with petechiae, accompanied by stuffiness in the heart, heart pain like pins and needles, and so on. If phlegm fire disturbs the heart, the tongue is red, the moss is yellowish and greasy, accompanied by palpitation (rapid heartbeat, often accompanied by panic), chest tightness and irritability, dry and bitter mouth. Chinese medicine treatment focuses on evidence-based treatment, myocarditis patients should receive systematic and comprehensive treatment in a timely manner, avoid exertion, pay attention to rest, and maintain a relaxed mood.
