Abstract: Atrial fibrillation is a prevalent rapid arrhythmia. Patients often develop kinesiophobia and avoidance behaviors due to reduced exercise tolerance and recurrent episodes of atrial fibrillation symptoms, which adversely affect cardiac rehabilitation outcomes. This study reviewed the definition, occurrence mechanisms, assessment tools, influencing factors, and intervention measures of kinesiophobia in patients with atrial fibrillation, aiming to provide references for implementing nursing practices and promoting exercise rehabilitation in these patients.
