【摘要】：目的探讨老年无心血管疾病髋关节置换手术患者围术期血压变异性(BPV)与阵发性心房颤动相关性及自主神经在阵发性心房颤动中的作用机制。方法在动态心电图及动态血压监测围术期新发房颤患者和正常患者BPV指标(24 h SBP、24 h DBP、24 h SSD、24 h DSD)、心率变异性(HRV)指标(TP、HF、LF、VLF、LF/HF)并对其进行统计学分析。结果房颤组术前BPV各项指标显著高于对照组,两组患者术后的血压均有所升高,随着血压的升高HRV也增高,房颤组显著高于对照组(P0.05);前房颤组HRV频域均低于对照组,其中LF、VLF在两组间差异最显著(P0.05)。术后两组HRV频域各指标均显著下降(P0.05),房颤组显著低于对照组(P0.05)。结论经受麻醉、手术创伤等应激后,老年患者易发生房颤,房颤患者BPV明显上升,而HRV明显降低,具有一定相关性。
[Abstract]:Objective to investigate the relationship between perioperative blood pressure variability (BPVV) and paroxysmal atrial fibrillation (PAF) and the role of autonomic nerve in paroxysmal atrial fibrillation (PAF) in elderly patients without cardiovascular disease. Ambulatory blood pressure (ABBP) was used to monitor the parameters of BPV in patients with new atrial fibrillation and normal patients in perioperative period: 24 h SBP, 24 h SSD, 24 h BPV, HRV) and their statistical analysis. Results the preoperative BPV indexes in AF group were significantly higher than those in control group. The blood pressure of the two groups increased after operation, with the increase of blood pressure, the HRV of AF group was significantly higher than that of control group (P 0.05), the frequency domain of HRV in anterior atrial fibrillation group was lower than that in control group. The frequency domain of HRV in the two groups was significantly lower than that in the control group (P 0.05). Conclusion after anaesthesia and surgical trauma, the elderly patients are prone to atrial fibrillation, and the BPV of the patients with atrial fibrillation is obviously increased. However, HRV was significantly decreased, which had certain correlation.
