《准绳》云∶悸即怔忡。今历观病状，则二证少有分别。悸则心中微动，如恐如
惊。怔忡则心胸振筑，莫知其来；忽尔宁寂，莫知其去。甚则头目眩晕，神气若浮，
盖悸之重者也。大抵因痰积饮停，气冲火击所致。（宜导痰汤、温胆汤、茯苓甘草汤、姜术汤之类。）
亦有中气虚而忡悸者。（宜补中益气汤、四君子汤、六君子汤、小建中汤、黄 建中汤之类。）亦有
心经气血不足，火不定，神不安而忡悸者。（宜四物汤、朱雀丸、当归补血汤、经验定心丹之类。）
有心液过耗，汗多亡阳，脉代而忡悸者。（宜炙甘草汤。）

According to *Zhunsheng* (Standard Guidelines): "Palpitation (Ji) is the same as severe palpitation (Zhongchong)." Upon reviewing clinical manifestations in modern practice, there is little distinction between these two syndromes. Ji (palpitation) presents as a slight trembling sensation in the heart region, resembling fear or fright. Zhongchong (severe palpitation) involves violent throbbing and pounding in the chest and heart area, with no clear indication of its onset; it suddenly subsides into silence, with no clear indication of its cessation. In severe cases, dizziness and vertigo of the head and eyes occur, and the Shen spirit appears floating; this represents the severe stage of Ji. Generally, these conditions are caused by the accumulation and retention of Phlegm-Fluids (Tan-Yin), where Qi rushes upward and Fire strikes internally. (Formulas such as Daotan Tang [Expel Phlegm Decoction], Wendan Tang [Warm the Gallbladder Decoction], Fuling Gancao Tang [Poria and Licorice Decoction], and Jiangzhu Tang [Ginger and Atractylodes Decoction] are appropriate.) There are also cases of Zhongchong and Ji caused by deficiency of Middle Qi. (Formulas such as Buzhong Yiqi Tang [Tonify the Middle and Augment the Qi Decoction], Sijunzi Tang [Four Gentlemen Decoction], Liujunzi Tang [Six Gentlemen Decoction], Xiaojianzhong Tang [Minor Construct the Middle Decoction], and Huangqi Jianzhong Tang [Astragalus Construct the Middle Decoction] are appropriate.) There are also cases caused by insufficiency of Qi and Blood in the Heart Meridian, where deficient Fire floats restlessly and the Shen spirit is unsettled. (Formulas such as Siwu Tang [Four Substances Decoction], Zhuque Wan [Vermilion Bird Pill], Danggui Buxue Tang [Angelica Tonify the Blood Decoction], and Jingyan Dingxin Dan [Experience-Based Heart-Calming Elixir] are appropriate.) There are cases where Heart Fluids are excessively depleted, excessive sweating leads to Yang collapse, and the pulse presents as intermittent (Dai Mai), resulting in Zhongchong and Ji. (Zhi Gancao Tang [Honey-Fried Licorice Decoction] is appropriate.)
