Bradyarrhythmia is a common clinical disease characterized by a marked decrease in heart rate. The etiology and pathogenesis of this disease are complex, and conditions such as coronary heart disease, various types of cardiomyopathies, cardiac degeneration, hypothyroidism, and others may contribute to its development. Some patients may show no obvious symptoms of discomfort, while others may experience symptoms such as shortness of breath and palpitations. In severe cases, patients may even faint, and the condition can become life-threatening. In recent years, with the continuous development of science and technology, there has been an increasing research focus on the etiology, pathogenesis, and diagnosis and treatment of bradyarrhythmia. This article summarizes the latest research progress on the etiology and treatment of bradyarrhythmia from the past decade, both domestically and internationally, aiming to provide guidance for clinical practice.
