Zhou, male, 33 years old, first visited on September 18, 1989. He had a duodenal bulb ulcer for 3 years, with persistent pain despite repeated treatments. Symptoms included gastric stuffiness after eating, fatigue, wilting impediment, reduced appetite, loose stools, gradually leading to flusteredness, shortness of breath, shallow yellow complexion, pale red tongue with thin greasy coating, and a slow, thin, and wiry pulse with a heart rate of 48 beats per minute. The ECG diagnosis was "sinus bradycardia." This was due to spleen-stomach weakness, with middle yang failing to circulate, leading to a lack of generation and transformation, and the heart losing its warmth and nourishment. The treatment method was to warm the middle and tonify qi, relieving urgency and stopping pain. Astragalus Center-Fortifying Decoction was prescribed, to be decocted with water and taken once daily. After taking 9 doses, all symptoms were resolved, the heart rate increased to 72 beats per minute, and the ECG returned to normal.
