ABSTRACT
Normal human blood pressure has a unique "dipper type" rhythm, but various pathological factors will lead to abnormal nighttime blood pressure decline, seriously damage the target organs such as the heart, brain and kidneys, and significantly increase the incidence of cardiovascular events. Therefore, it is necessary to pay sufficient attention to rhythm disorder of blood pressure and intervene early. Modern Traditional Chinese Medicine (TCM) mostly understands the changes of rhythm of blood pressure from the view of the unity of nature and man, yin-yang theory and the theory of meridian flow, and study the syndrome distribution and TCM constitution law of rhythm disorder of blood pressure by combining TCM syndrome differentiation method and TCM constitution theory. TCM treatment can restore blood pressure rhythm and improve clinical symptoms and sleep quality of patients.
