Abstract:
Cardiac deficiency of qi(vital energy) is one of the main syndromes in terms of TCM (Traditional Chinese Medicine). Based on our analysis of blood-tissue fluid circulation, we set up a hemodynamics model describing cardiac deficiency of qi. The model's theoretical results can reflect the manifestations of cardiac deficiency of qi, and are identical to those of clinical experimental discoveries, therefore it has substantiated our theory-cell's abnormal physiological function caused by undernourishment of tissue fluid is the reason of qi-deficiency.
