Abstract:Bradyarrhythmia is a disease characterized by slow heart rate. The prevalence rate of bradyarrhythmia has increased in recent years, which seriously affects human life and may induce sudden death. The establishment of scientific and stable animal models is conducive to further research and prevention of bradyarrhythmia. Currently, the models of bradyarrhythmia mainly include induced animal models, mechanical stimulation animal models, electrical stimulation animal models, radiofrequency ablation animal models, etc. Various modeling methods have advantages and disadvantages, and more efficient and reasonable animal models are required in the future.
