Syndromes of Qi, blood, and body fluid disorders

Traditional Chinese Medicine Definition

In traditional Chinese medicine, syncope, also known as fainting, is a type of disease related to Qi, blood, and body fluid imbalances. According to the "Internal Medicine of Traditional Chinese Medicine," syncope refers to a condition where Qi flow is disrupted, leading to the separation of Yin and Yang, resulting in sudden fainting and loss of consciousness. The characteristics of syncope include an abrupt onset, critical condition, and etiology often related to emotional disturbances, imbalance of work and rest, and improper diet.

In clinical practice of traditional Chinese medicine, the core pathogenesis of syncope is the disruption of Qi flow and the imbalance of Yin and Yang. Common precipitating factors include extreme emotions, excessive sexual activity, and irregular diet. During the differential diagnosis, attention should be paid to distinguishing between cold and heat, deficiency and excess. For instance, the excess pattern of Qi syncope is characterized by sudden fainting, loss of consciousness, locked jaw, and rough breathing; while the excess pattern of blood syncope presents with sudden fainting, flushed face, purple lips, and a closed jaw. The overall approach to treatment suggests smoothing Qi and opening up stagnation, or calming the Liver and subduing Yang, along with regulating Qi and promoting blood circulation. In clinical practice, the treatment of syncope emphasizes harmonizing Yin and Yang, restoring Qi flow, and preventing further deterioration of the condition. Traditional Chinese medicine believes that through differential diagnosis and treatment, symptoms can be alleviated and recurrence prevented.
