心电图检查可提供尘肺合并肺心病早期诊断的线索,也可了解尘肺对心脏影响的程度,为临床诊断、治疗提供了可靠的依据。本文对323例住院的尘肺病人心电图分析如下。1 资料与方法1.1 资料来源于1977～1997年在我院住院的接触粉尘的男性尘肺患者323例年龄30～71岁,平均年龄47岁,其中Ⅰ期尘肺104人,Ⅱ期尘肺162人,Ⅲ期尘肺57人。对照组随机选择不接触有害物质的健康体检的男性330人,年龄28～73岁,平均年龄48.1岁。1.2 方法 用日本产ECG-6511型心电图机,对受检查者作常常9—12个导联的心电图描记。由专人负责按心电图诊断标准
ECG examination can provide clues to the early diagnosis of pneumoconiosis complicated with pulmonary heart disease, but also understand the extent of pneumoconiosis on the heart, providing a reliable basis for clinical diagnosis and treatment. In this paper, 323 cases of hospitalized patients with pneumoconiosis ECG is as follows. 1 Materials and Methods 1.1 Data from 1977 to 1997 were hospitalized in our hospital dust-exposed male patients with pneumoconiosis 323 were aged 30 to 71 years, mean age 47 years, of which 104 were stage I pneumoconiosis, 162 pneumoconiosis Ⅱ, Ⅲ 57 cases of pneumoconiosis. In the control group, 330 males, aged from 28 to 73 years with a mean age of 48.1 years, were randomly selected to have a healthy physical examination without exposure to harmful substances. 1.2 Methods Japanese-made ECG-6511-type ECG machine, the subjects were often made 9-12 lead ECG.
