“…Early diagnosis and effective arrhythmia management have shown considerable potential in improving ventricular function and alleviating clinical symptoms. Prompt identification of electromechanical dysfunction in individuals with a normal left ventricular ejection fraction is now achievable through the assessment of cardiac electrical and mechanical function using acoustic cardiography (ACG)[ 13 , 14 ]. The ACG serves as a valuable early screening tool for heart failure.…”

BACKGROUND 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. CASE SUMMARY A woman who presented with postactivity fatigue and dyspnea was diagnosed with bradycardia at the age of 7. Since she had no obvious symptoms, she did not receive any treatment to improve her bradycardia during the 42-year follow-up, except for the implantation of a temporary pacemaker during labor induction surgery. As time progressed, the patient's heart gradually expanded due to her low ventricular rate, and she was diagnosed with BIC. In 2014, the patient developed atrial fibrillation, her ventricular rate gradually increased, and her heart shape gradually returned to normal. This report describes the cardiac morphological changes caused by the heart rate changes in BIC patients older than 40 years, introduces another possible outcome of BIC, and emphasizes the importance of early intervention in treating BIC. CONCLUSION BIC can induce atrial fibrillation, causing an increased ventricular rate and leading to positive cardiac remodeling.
