Patients with hyperthyroidism or hypothyroidism are often combined with atrial fibrillation, but after the stabilization of thyroid hormone levels after treatment, the patients' atrial fibrillation still persists. Radiofrequency ablation of the atrial fibrillation as one of the treatment options for atrial fibrillation has been widely used in the clinic, and has significant efficacy in maintaining sinus rhythm, improving cardiac function, and improving the prognosis of patients. However, there is a lack of clinical monitoring data on radiofrequency ablation of atrial fibrillation in patients who have combined thyroid dysfunction and have stabilized their thyroid hormone levels after treatment.
In patients recommended by guidelines for atrial catheter radiofrequency ablation of atrial fibrillation, catheter radiofrequency ablation was performed after exclusion of contraindications, and was observed and compared between patients with comorbid pre-existing thyroid hormone disorders and patients without comorbid atrial fibrillation after radiofrequency ablation:1: time to sexual rhythm maintenance: incidence of cardiac-related complications and incidence of noncardiac-related complications within 3 months and 1 year,2: walking distance on a six-minute walk test within 3 months,1 year, comparison of percent left ventricular ejection fraction, and comparison of left ventricular diastolic diameter at the time 3 months,1 year,.To comprehensively assess the efficacy and safety of catheterized radiofrequency ablation of atrial fibrillation in patients with comorbidities of prior thyroid hormone disorders.
