目的:自主神经失平衡在阵发性心房颤动起重要作用,该研究探索经皮耳迷走神经刺激(ta-VNS)在肺静脉隔离(PVI)术中有效性.方法:按照纳入标准及排除标准,连续入组阵发性心房颤动射频消融患者,共入组120例心房颤动患者,平均年龄(64.3±8.6)岁.随机分2组,观察组(PVI+ta-VNS)和对照组(PVI+假ta-VNS)各60例.使用华佗刺激仪于耳迷走神经区域进行刺激,刺激时间为整个消融过程.主要终点:单次消融后,空白期至随访结束,无心房颤动复发患者的比例.每3个月进行门诊/电话随访,第12月中期分析.结果:中位随访时间16.5个月,12个月无心房颤动发生率在观察组和对照组分别81.6%和70%(P<0.05).结论:在阵发性心房颤动的PVI+ta-VNS较PVI+假ta-VNS更有效和更安全.
Randomized Controlled Study on the Safety and Efficacy of Low-Frequency Transcutaneous Auricular Vagus Nerve Stimulation During Pulmonary Vein Isolation for Paroxysmal Atrial Fibrillation
Objective:Autonomic imbalance plays a significant role in paroxysmal atrial fibrillation(PAF).This study investigates the efficacy of transcutaneous auricular vagus nerve stimulation(ta-VNS)during pulmonary vein isolation(PVI)procedures.Methods:Following inclusion and exclusion criteria,120 patients with paroxysmal atrial fibrillation undergoing radiofrequency ablation were consecutively enrolled,with an average age of(64.3±8.6)years.They were randomly divided into two groups:the observation group(PVI + ta-VNS)and the control group(PVI + sham ta-VNS),with 60 patients in each.Stimulation of the auricular vagus nerve region was conducted using a Hua Tuo stimulator throughout the ablation process.The primary endpoint was the proportion of patients without atrial fibrillation recurrence after a single ablation procedure,up to the end of the follow-up period.Follow-up was conducted every 3 months through outpatient visits or phone calls,with an interim analysis at 12 months.Results:The median follow-up time was 16.5 months,with a 12-month atrial fibrillation-free rate of 81.6%in the observation group and 70%in the control group(P<0.05).Conclusion:PVI + ta-VNS is more effective and safer than PVI + sham ta-VNS in patients with paroxysmal atrial fibrillation.
