摘要：
Myocardial bridging (MB) is a congenital anomaly characterized by systolic compression of the tunnelled arterial segment. MB may cause myocardial ischaemia due to abnormal coronary blood flow. We report a case of MB in which transthoracic Doppler echocardiography was used to evaluate the long-term effect of beta-blocker therapy on abnormal coronary blood flow. In this case, beta-blocker therapy with bisoprolol (5.0 mg/day) for 1 month eliminated the patient's symptoms and normalized coronary blood flow through the tunnelled arterial segment.
