摘要
目的：探讨结核患者心率变异性与早搏的关系。方法收集111例结核患者的24 h动态心电图，并常规分析心率变异性的各项时域指标，根据早搏频率将其分为对照组（0～10次/24 h）、偶发组（11～500次/24 h）和频发组（＞500次/24 h）。结果①偶发组与对照组比较，除HRVTI 差异有统计学意义（P＜0．05）外，其他指标 SDNN、SDANN、SDNN index、PNN50和rMSSD差异均无统计学意义（P＞0．05）。频发组与对照组比较，SDNN、SDANN、SDNN index、PNN50和HRVTI差异均有统计学意义（P＜0．05）；rMSSD 差异无统计学意义（P＞0．05）。偶发组和频发组比较，SDNN 和SDANN 差异有统计学意义（P＜0．05）；SDNN index、PNN50、rMSSD和HRVTI差异均无统计学意义（P＞0．05）。②频发组与对照组、频发组与偶发组比较，SDNN和HRVTI阳性率差异均有统计学意义（P＜0．05）；偶发组与对照组比较，SDNN和HRVTI阳性率差异无统计学意义（P＞0．05）。结论心率变异性的降低与早搏频发之间具有内在联系，这对预测高危早搏结核患者的预后具有重要的临床意义。
Objective Toexploretherelationshipbetweenheartratevariabilityandpremature beatforpatientswithtuberculosis.Methods Twenty-four-hourambulatoryelectrocardiographyof 1 1 1 tuberculosis patients were selected and kinds of time-domain indices of heart rate variability were routinely analyzed.According to frequency of premature beat,the enrolled cases were divided into control group（0-1 0 times per 24 hours）,sporadic group（1 1 -500 times per 24 hours）and frequent group （＆gt;500 times per 24 hours ）.Results ① Between sporadic group and control group,there weren’t statistically significant differences in other indices including SDNN,SDANN, SDNN index,PNN50 and rMSSD（P〉0.05 ）,except for statistically significant difference in HRVTI （P〈0.05）.Between frequent group and control group,differences of SDNN,SDANN,SDNN in-dex,PNN50 and HRVTI were all statistically significant（P〈0.05 ）while that of rMSSD wasn’t statistically significant（P〉0.05）.Between sporadic group and frequent group,there existed statis-tically significant differences in SDNN and SDANN （P〈0.05 ）while there existed no statistically significant differences in SDNN index,PNN50,rMSSD and HRVTI（P〉0.05）.② Between fre-quent group and control group as well as frequent group and sporadic group,there all existed statisti-cally significant differences in positive rates of SDNN and HRVTI（P〈0.05）.And yet the differ-ences of positive rates of SDNN and HRVTI weren’t statistically significant（P〉0.05）between sporadicgroupandcontrolgroup.Conclusion Thedecreaseofheartratevariabilityisinherentlyrelat-ed to frequent premature beat,which offers important clinical significance in predicting the prognosis of tuberculosis patients at a high risk of premature beat.
