摘要
目的探讨扩张型心肌病(DCM)患者心电图碎裂QRS(fQRS)波的临床价值。方法回顾性分析112例符合DCM诊断标准的患者,根据12导联心电图上是否存在fQRS波和QRS的时限,将入选患者分为碎裂QRS波组(fQRS组)、宽QRS波组(wQRS组)和非碎裂QRS波组(nonfQRS组),比较fQRS波在DCM患者和健康对照组的发生率;比较观察组3种QRS波形态的发生率,比较fQRS组、wQRS组和nonfQRS组的患者左室射血分数(LVEF)降低、室性心律失常、心源性休克、心源性死亡的发生率。结果观察组中fQRS波发生率显著高于健康对照组(P<0.01);观察组中fQRS波和wQRS波的发生率显著高于nonfQRS波的发生率(P<0.05);fQRS组和wQRS组的LVEF降低、室性心律失常、心源性死亡的发生率明显高于nonfQRS组(P<0.05)。结论在有DCM诊断的其他证据时,fQRS波可作为心电图诊断DCM的一个新指标,并可作为早期识别DCM高危人群的指标之一。
Objective To explore the clinical value of fragmented QRS complex （fQRS） in patients with dilated cardiomyopathy（DCM）.Methods Retrospectively analyse 112 patients suitable for DCM diagnostic criteria. According to the existence of fQRS complex in 12 lead ECG and duration of QRS complex, divide them into fQRS group, wide-QRS （wQRS） group and non-fragmented-QRS （nonfQRS） group, and then compare the incidence rate of fQRS between DCM patients and the control group. In addition, the incidence rates of the decrease of left ventricular ejection fraction（LVEF） and ventricular arrhythmia and cardiogenic shock and cardiac death of patients with fQRS, wQRS and nonfQRS were also compared.Results TThe incidence rate of fQRS in the observation group was significantly higher than that of control group（P0.01）. Among the observation group, the incidence rates of fQRS and wQRS were noticeably higher than that of nonfQRS group（P0.05）. In aspects of the incidence rates of the decrease of LVEF and ventricular arrhythmia and cardiac death, those two groups were also higher than nonfQRS group（P0.05）.Conclusion Besides other evidences to diagnose DCM, fQRS could serve as a new indicator for the diagnosis of DCM, which can also be considered as one of the early indicators for DCM high-risk population.
