Bradycardia-induced cardiomyopathy (BIC), which is a disease resulting from bradycardia, is characterized by cardiac chamber enlargement and diminished cardiac function. The correction of bradycardia can allow for significant improvements in both cardiac function and structure; however, this disease has been infrequently documented. In this case, we conducted a longitudinal follow-up of a patient who had been enduring BIC for more than 40 years to heighten awareness and prompt timely diagnosis and rational intervention.

房颤患者的心脏重塑逆转心动过缓诱发的心肌病：病例报告。

心动过缓诱发的心肌病（BIC）是一种由心动过缓引起的疾病，其特征是心腔扩大和心功能减弱。纠正心动过缓可以显着改善心脏功能和结构；然而，这种疾病很少有记录。本例中，我们对一位患有BIC 40多年的患者进行了纵向随访，以提高认识，促使及时诊断和合理干预。
