摘要
目的研究碎裂QRS(fragmented QRS,fQRS)波在肺栓塞诊断中的临床价值。方法 120名肺栓塞患者作为实验组,120名健康人作为对照组,均在进行静息状态下12导联心电图检查,分析实验组和对照组fQRS波的发生情况。结果实验组fQRS波发生率高于对照组,差异具有统计学意义(χ2=53.01,P<0.05)。fQRS波在高危组、中危组和低危组发生率分别为49.35%、31.17%、19.48%,非fQRS波在高危组、中危组和低危组发生率分别为13.95%、34.88%和51.16%,差异具有统计学意义(χ2=14.52,P<0.05)。结论 fQRS波在肺栓塞患者中出现频率明显升高,并且在危险度分层较高的患者中出现的频率更高,表明fQRS波在肺栓塞的诊断和病情判断中具有一定的临床价值。
Objective To study the clinical value of fragmented QRS（ fQRS） wave in diagnosis of pulmonary embolism. Methods 120 patients with pulmonary embolism were divided as the experimental group,120 healthy people were divided as control group,the experimental group and control group were in a resting 12lead ECG examination,the experimental group and the control group fQRS wave were analyzed. Results In the experimental group,the incidence rate of fQRS wave was higher than in the control group,the difference was statistically significant（ χ2= 53. 01,P ＆lt; 0. 05）. FQRS wave in high risk group,medium risk group and low risk group were 49. 35%,31. 17%,19. 48%,non fQRS wave in high risk group,medium risk group and low risk group were 13. 95%,34. 88% and 51. 16%,the difference was statistically significant（ χ2= 14. 52,P ＆lt; 0. 05）.Conclusions fQRS wave frequency significantly increased in patients with pulmonary embolism,and emerged in risk stratification in patients with higher frequency is higher,shows that it has a certain clinical value of fQRS wave in the diagnosis of pulmonary embolism and condition judgment.
