伤寒所致的心悸，是指心下部有悸动感。这通常是因为患伤寒病后，先使用了发汗法，随后又误用了泻下法。体内因虚而生热则口渴，口渴饮水后必然感到胃脘部拘急不适。如果脉象洪大且数，按照常规应当通过出汗而痊愈；但误用泻下法后，身体沉重，心中必然悸动。此时不可再发汗，应当等待其自然出汗而解。

Palpitations caused by Cold Damage (Shanghan) refer to a sensation of palpitation in the epigastrium. This condition arises from contracting Cold Damage, followed first by sweating therapy and subsequently by mistaken purgation. Internal deficiency-heat leads to thirst; upon drinking water, there is inevitably discomfort and urgency in the interior. If the pulse is surging and rapid, recovery should normally occur through sweating. However, after mistaken purgation, the body feels heavy, and the heart must palpitate. Sweating therapy is contraindicated at this stage; one should wait for spontaneous sweating to resolve the condition.
For Cold Damage lasting two to three days, characterized by palpitations in the heart region, incessant vomiting, mental anxiety, depression, and slight irritability, indicating that the pathogen has not yet resolved, Da Chai Hu Tang (Major Bupleurum Decoction) may be administered.
