Throbbing Pulse (动脉)

Appearance (体象歌)

动无头尾，其动如豆；厥厥动摇，必兼滑数。

Clinical Indications (主病歌)

动脉主痛，亦主于惊。左寸得动，惊悸可断；右寸得动，自汗无疑。左关若动，惊及拘挛；右关若动，心脾疼痛。左尺见之，亡精为病；右尺见之，龙火奋迅。

Clinical Significance

The Throbbing Pulse indicates pain and fright or palpitations. Its form is short, slippery, and rapid, beating like a bean under the finger with a restless, shaking movement. It forms when yin and yang contend, qi and blood rebel, or when severe pain or sudden fright causes qi and blood to surge locally in the vessel. The Throbbing Pulse usually appears at the guan position but can also be felt at the inch and chi positions, suggesting qi stagnation and acute pain. At the left inch position, throbbing pulse indicates heart spirit disturbed by fright with palpitations, insomnia, and frequent startling. At the right inch, it reflects insecure lung wei with spontaneous sweating, shortness of breath, and easy startling. At the left guan, it points to internal stirring of liver wind or muscular cramps with convulsions, tremors, and startling. At the right guan, it indicates heart-spleen disharmony with qi rebellion, presenting as stomach or chest pain, belching, and nausea. At the left chi, it reflects kidney yin deficiency with insecure essence gate, presenting as seminal emission and nocturnal emissions. At the right chi, it indicates ministerial fire stirring with seminal emission, yellow leukorrhea, lower leg sores, and restless sleep. Sudden emotional shock or physical trauma can trigger this pulse even in otherwise healthy individuals, and reassurance and a stable environment play important roles in settling the heart spirit and calming the pulse.

Treatment and Care

For fright and palpitations with a Throbbing Pulse, treatment calms the spirit, nourishes blood, and stabilizes willpower. Heart deficiency and gallbladder timidity with palpitations and insomnia are treated with An Shen Ding Zhi Wan or Suan Zao Ren Tang. Heart-spleen deficiency is treated with Gui Pi Tang. Internal stirring of liver wind with convulsions and cramps is treated with Ling Jiao Gou Teng Tang or Zhen Gan Xi Feng Tang to calm the liver and extinguish wind. For severe pain, treat according to the location and nature of pain using blood-activating, qi-regulating, cold-scattering, or channel-unblocking formulas such as Dan Shen Yin, Shi Xiao San, or Jin Ling Zi San. For kidney essence deficiency with insecure essence gate, nourish yin and secure essence with Jin Suo Gu Jing Wan or Zhi Bai Di Huang Wan. Daily care emphasizes a quiet environment, avoiding sudden noises; warm foot baths before bed and nourishing foods such as warm milk or longan to calm the heart spirit; and avoiding frightening or stimulating content. Sitting meditation and deep breathing stabilize the spirit, and moxibustion at Shen Men, Nei Guan, and San Yin Jiao helps calm the heart and spirit. Reducing caffeine and other stimulants helps prevent further disturbance of the heart spirit and sleep, and gentle routines and predictable daily rhythms support recovery from fright and stabilize the autonomic system.
