A patient in their 60s was hospitalized with upper right quadrant discomfort for more than 10 days. The patient had a history of gastric cancer. Ultrasonography at a local hospital revealed multiple low-density foci in the liver. The patient had a history of coronary heart disease and had undergone a percutaneous coronary intervention at another hospital 1 year prior; the details were unknown. Laboratory examination showed a carcinoembryonic antigen level of 8.34 ng/mL (to convert to μg/L, multiply by 1.0) and an α-fetoprotein level of 9.97 ng/mL (to convert to μg/L, multiply by 1.0). Myocardial enzyme examination showed no abnormalities. During the course of the disease, the patient had no symptoms, such as chest tightness, chest pain, or syncope. After admission, two 12-lead electrocardiogram (ECG) examinations were performed (Figure). The Figure, A shows complete right bundle-branch block (CRBBB) with left anterior fascicular block (LAFB), though the second ECG (Figure, B) suggests CRBBB with left posterior fascicular block (LPFB).
