（是经起于天池穴，终于中冲穴。）
心主手厥阴心包络之脉，起于胸中，出属心包络，下膈，历络三焦。其支者，循胸中出胁，下腋三寸，上
抵腋，下循 内，行太阴、少阴之间，入肘中，下臂行两筋之间，入掌中，循中指出其端。其支者，别掌中，
循小指次指出其端。是动则病手心热，臂肘挛急，腋肿，甚则胸胁支满，心中 大动，面赤目黄，喜笑不休
。是主脉所生病者，烦心心痛，掌中热。为此诸病，盛则泻之，虚则补之，热则疾之，寒则留之，陷下则灸之，
不盛不虚，以经取之。盛者寸口大一倍于人迎，虚者寸口反小于人迎也。
小指次指，即手小指之次指，乃无名指也。
手厥阴心包络经之脉，受足少阴肾经之交，起于胸中，出属心下之包络，由是下膈，历络于三焦。其支者
，自属心包，上循胸，出胁下腋三寸天池穴，上行抵腋，下循 内之天泉，以界手太阴肺经、手少阴心经两经
之中间，入肘中之曲泽穴，又由肘中下臂，行臂两筋之间，循 门、间使、内关、大陵，入掌中劳宫，循中指
出其端之中冲穴。其支别者，从掌中循无名指出其端，而交于手少阳三焦经也。
(The meridian starts at Tianchi (PC1) and ends at Zhongchong (PC9).)
The Pericardium Meridian of Hand-Jueyin originates in the chest, emerges to connect with the Pericardium, descends through the diaphragm, and successively connects with the Triple Energizer. Its branch follows the chest, emerges from the hypochondrium, descends three cun below the axilla, ascends to reach the axilla, and then descends along the medial aspect of the upper arm, running between the Lung Meridian of Hand-Taiyin and the Heart Meridian of Hand-Shaoyin. It enters the elbow, descends along the forearm between the two tendons, enters the palm, and follows the middle finger to its tip. Another branch separates from the palm, follows the ring finger to its tip. When this meridian is affected, it causes heat in the palm, spasm and stiffness of the arm and elbow, swelling of the axilla; in severe cases, it causes a feeling of fullness and distension in the chest and hypochondrium, violent palpitations, red face, yellow eyes, and incessant laughter. This meridian governs diseases related to the vessels, such as vexation, heart pain, and heat in the palm. For these conditions, excess is drained, deficiency is supplemented, heat is treated with rapid needling, cold is treated with retained needling, sinking qi is treated with moxibustion, and neither-excess-nor-deficiency conditions are treated by selecting points on the meridian itself. Excess is indicated when the pulse at Cun Kou is one times larger than that at Ren Ying; deficiency is indicated when the pulse at Cun Kou is smaller than that at Ren Ying.
"Xiao Zhi Ci Zhi" refers to the finger adjacent to the little finger, which is the ring finger.
The Pericardium Meridian of Hand-Jueyin intersects with the Kidney Meridian of Foot-Shaoyin. It originates in the chest, emerges to connect with the pericardium located below the heart, descends through the diaphragm, and successively connects with the Triple Energizer. Its branch, starting from the connection with the pericardium, ascends along the chest, emerges from the hypochondrium to descend three cun below the axilla to Tianchi (PC1), ascends to reach the axilla, and descends along Tianquan (PC2) on the medial aspect of the upper arm, positioned between the Lung Meridian of Hand-Taiyin and the Heart Meridian of Hand-Shaoyin. It enters Quze (PC3) in the elbow, then descends along the forearm between the two tendons, passing through Ximen (PC4), Jianshi (PC5), Neiguan (PC6), and Daling (PC7), entering Laogong (PC8) in the palm, and following the middle finger to its tip, Zhongchong (PC9). The separate branch from the palm follows the ring finger to its tip, thereby connecting with the Sanjiao Meridian of Hand-Shaoyang.
The Collateral of the Pericardium of Hand-Jueyin. It consists of nine acupoints. Starting from Tianchi (PC1) and Tianquan (PC2), it sequentially passes through Quze (PC3) and Ximen (PC4); Jianshi (PC5) connects to Neiguan (PC6); Daling (PC7) is near Laogong (PC8); finally, from the center of the palm, it reaches Zhongchong (PC9).
