The clinical manifestations of biliary heart syndrome are precordial pain, arrhythmia, and electrocardiographic changes. 1. Anterior cardiac pain: biliary tract diseases produce involvement pain through the visceral nerves, with varying degrees of dullness and colic in the anterior cardiac region or epigastric region. It lasts for a long time, often occurs after eating fatty food, and is ineffective when nitroglycerin is included. 2. Arrhythmia: Because arrhythmia often feel palpitations, panic. It may be related to the biliary tract disease through the autonomic nerves, especially the vagus nerve, leading to the heart autoregulation disorder. The arrhythmia will disappear after the biliary tract disease is cured. 3. Electrocardiographic changes: Non-specific ST-segment depression and T-wave inversion are seen in about one-third of patients. The cardiac symptoms and electrocardiographic changes of biliary heart syndrome are similar to those of coronary artery disease and angina pectoris, and are easily misdiagnosed. If the above symptoms occur, it is recommended to consult a doctor in time and standardize the treatment under the doctor’s guidance.
