《黄帝内经·素问·藏气法时论》
患有心病的人，愈于戊已日，如果戊已日不愈，到壬癸日病就加重，如果在壬癸日不死，到甲乙日病情就会维持稳定不变状态，到丙丁日病即好转。
心病者，愈在戊己，戊己不愈，加于壬癸，壬癸不死，持于甲乙，起于丙丁。
Heart diseases will get better on Wuji days. If the condition remains the same on Wuji days, it will worsen on Renkui days. If the patient survives Renkui days, the condition will remain stable on Jia and Yi days and will begin to improve on Bingding days.
