The circadian rhythm of Yin and Yang Syndrome on hypertension

Objective: To study the relationship between the circadian rhythm of Yin and Yang Syndrome on essential hypertension.Methods: The noninvasive ambulatory blood pressure monitoring was used in the clinical evaluation of 84 hypertensive inpatients.Results: The profile of ambulatory blood pressure in traditional Chinese medicine is characterized by the usual nocturnal decline in blood pressure, as well as by a prominent secondary fall in the early afternoon. The blood pressure to be highest is at Chen ( tic, 11:00am). The inverse circadian blood pressure is discovered in spontaneously hypertension rats (SHR).Conclusion: The pathogenesis of hypertension is due to the excessive Yang that is caused by incoordination between Yin and Yang. The TCM pattern differentiation of hypertension can be identified by Yin and Yang.
