摘　　要：目的探讨常规12导联心电图胸导联QRS波低电压患者的临床特征。方法回顾性分析住院期间行常规12导联心电图检查并诊断为胸导联低电压的131例患者的临床资料,并观察其临床特征。结果131例患者中有65例(49.62%)为全胸导联低电压,52例(39.69%)合并全肢体导联低电压。基础疾病以冠心病伴心功能不全最多,共计26例(19.85%);其次为恶性肿瘤,共计23例(17.56%),其中以肺癌患者居多,为9例(6.87%)。45例(34.35%)合并贫血,40例(30.53%)合并低蛋白血症。所有入选患者的血红蛋白及血白蛋白浓度的平均值都低于正常范围。结论冠心病伴心功能不全为常规12导联心电图胸导联QRS波低电压患者最常见的基础疾病,且大部分患者患有影响QRS波电压的并发症。Objective To investigate the clinical characteristics of patients with low QRS voltage in precordial leads of routine 12-lead ECG.Methods Retrospective analysis was performed on 131 patients examined by routine 12-lead ECG and diagnosed with low voltage in precordial leads during hospitalization.We observed their clinical characteristics.Results Among the 131 patients,there are 65 cases(49.62%)with low voltage in all precordial leads,and 52 cases(39.69%)with low voltage in all limb leads.Coronary heart disease complicated by cardiac insufficiency is the most common underlying disease(26 cases,accounting for 19.85%),followed by malignant tumor(23 cases,accounting for 17.56%)among which lung cancer accounts for the largest proportion(9 cases,accounting for 6.87%).A total of 45 cases(34.35%)are accompanied with anemia and 40 cases(30.53%)are complicated by hypoproteinemia.The average level of blood hemoglobin and blood albumin are both below the normal range.Conclusion Coronary heart disease complicating cardiac insufficiency is the most common underlying disease of patients with low QRS voltage in precordial leads of routine 12-lead ECG,and most of these patients have complications affecting QRS voltage.
