摘　　要：目的探讨心电图低电压改变的临床意义和病因。方法收集体表心电图诊断的132例低电压患者的临床资料,分析病因和患者临床特点。结果 1 132例患者中胸导联低电压32例(24%),肢体导联低电压87例(66%),肢体导联合并胸导联低电压13例(10%);2肿瘤并发心电图低电压者69例(52%),以肺癌发病率最高;3心功能不全患者中,前壁心肌梗死和扩张型心肌病为主要病因。结论恶性肿瘤并发的心电图低电压为临床最常见原因。Objective To explore the clinical significance and pathogeny of low voltage changes on ECG.Methods The data of 132 patients were collected who were diagnosed with low voltage by surface ECG and were in hospital from June 2013 to March 2014.Their pathogeny and clinical char-acteristics were analysed.Results ① Among the 132 patients,there were 32 patients（24%）with precordial low voltage,87 （66%）with limb low voltage,and 13 （10%）with both precordial and limb low voltage.② Sixty-nine patients（52%）suffered from cancers,lung cancer ranking at the first place.③ Of all the patients with cardiac functional insufficiency,anterior wall infarction and dilated cardiomyopathy were the main causes of diseases.Conclusion Cancers might be the main causes of low voltage on ECG.
