【摘要】：目的探討原發(fā)性高血壓病患者交感神經(jīng)、迷走神經(jīng)張力變化對(duì)靜息心率(RHR)的影響。方法選取2013年于武漢市第一醫(yī)院門診及住院治療的原發(fā)性高血壓病患者404例為研究對(duì)象。記錄標(biāo)準(zhǔn)12導(dǎo)聯(lián)心電圖,用平均RR間期計(jì)算出RHR。根據(jù)RHR,將患者分為RHR-L組(60次/min)、RHR-M組(60~75次/min)和RHR-H組(≥75次/min)。隨即接受24 h動(dòng)態(tài)心電圖記錄,離線應(yīng)用動(dòng)態(tài)心電記錄分析系統(tǒng),計(jì)算極低頻帶(VLF)、低頻帶(LF)、高頻帶(HF)、心率減速力(DC)值。結(jié)果各組VLF、LF、HF、DC、LF/HF比較,差異均有統(tǒng)計(jì)學(xué)意義(P0.05);其中,RHR-M組VLF、LF、HF低于RHR-L組,RHR-H組VLF、LF、HF、DC低于RHR-L組、RHR-M組,RHR-H組LF/HF高于RHR-L組、RHR-M組(P0.05)。RHR與VLF[r=-0.436,95%CI(-0.501,-0.369)]、LF[r=-0.290,95%CI(-0.378,-0.205)]、HF[r=-0.394,95%CI(-0.468,-0.315)]、DC[r=-0.219,95%CI(-0.310,-0.123)]呈負(fù)相關(guān)(P0.001),與LF/HF[r=0.248,95%CI(0.158,0.332)]呈正相關(guān)(P0.001)。多因素線性回歸分析顯示,VLF、HF、LF/HF是原發(fā)性高血壓病患者RHR的影響因素(P0.05)。結(jié)論 RHR為60~75次/min的原發(fā)性高血壓病患者RHR主要受到迷走神經(jīng)紊亂影響,而RHR≥75次/min的患者RHR則主要受到交感神經(jīng)系統(tǒng)紊亂影響。
[Abstract]:Objective to investigate the effect of sympathetic and vagal nerve tension on resting heart rate (RHR) in patients with essential hypertension. Methods 404 patients with essential hypertension were selected from outpatient and inpatient department of Wuhan first Hospital in 2013. The standard 12 lead electrocardiogram was recorded and the mean RR interval was used to calculate RHRs. According to RHRs, patients were divided into two groups: RHR-L group (60 times / min) and RHR-H group (鈮，
