Core Tip

Core Tip: Bradycardia-induced cardiomyopathy (BIC) is a disease caused by bradycardia and characterized by enlargement of the heart chambers and decreased cardiac function. Increasing the ventricular rate significantly improved the associated symptoms and cardiac remodeling; however, this disease has rarely been reported. This case report describes a woman with BIC who, with little therapeutic intervention to improve bradycardia, had an increase in her ventricular rate due to the onset of atrial fibrillation, after which her cardiac enlargement due to a low ventricular rate was reversed. This case also emphasized the importance of early intervention for BIC.
