To compare the incidence of atrial fibrillation (AF) and alteration of heart rate variability (HRV) after pulmonary lobectomy through video assisted thoracic surgery or thoracotomy, and to explore the role of autonomic nerves in the pathogenesis of atrial fibrillation after pulmonary lobectomy.
In a single institution, 224 patients (age > 60) with normal sinus rhythm were enrolled in the study. Experienced surgeons and anesthetists carried out operation and anesthesia according to the same procedure. The hearts were monitored using Holter for more than 96 h. Any new-onset AF was recorded and HRV was analyzed at different time intervals.
One hundred twelve patients undergoing video-assisted thoracic surgery (VATS) and 112 patients undergoing thoracotomy (THOR) were matched for age and gender. Atrial fibrillation occurred in 39 patients, with a similar incidence between the two groups (VATS: 19/112, 16.9% and THOR: 20/112, 17.9%, P = 0.82). The post-operational heart variability at different time intervals was comparable between the two groups.
Pulmonary lobectomy through video assisted thoracic surgery does not reduce the postoperative atrial fibrillation. Autonomic nerve mechanism may be involved in the pathogenesis of postoperative atrial fibrillation.
比较电视辅助胸腔镜手术或开胸肺叶切除术后房颤(AF)的发生率及心率变异性(HRV)的改变,探讨自主神经在肺叶切除术后房颤发病机制中的作用。
在单一机构中,纳入224例年龄>60岁、窦性心律正常的患者进行研究。经验丰富的外科医生和麻醉师按照相同程序进行手术和麻醉。使用动态心电图监测心脏超过96小时。记录任何新发房颤情况,并在不同时间间隔分析HRV。
112例行电视辅助胸腔镜手术(VATS)的患者和112例行开胸手术(THOR)的患者在年龄和性别上相匹配。39例患者发生房颤,两组发生率相似(VATS组:19/112,16.9%;THOR组:20/112,17.9%,P = 0.82)。两组在不同时间间隔的术后心脏变异性相当。
电视辅助胸腔镜肺叶切除术不会降低术后房颤的发生率。自主神经机制可能参与了术后房颤的发病过程。
