心电图能敏感地反映出慢性阻塞性肺部疾病(COLD)及肺气肿。大致包括向量与振幅的改变。作者多年来在临床工作中曾注意到COLD患者心电图中QRS时限有缩短的趋向,但遍查文献未有此类研究数据。作者随将55名男性COLD患者(平均年龄为58.9岁,经临床、X线及肺功能测验证实)以及另外年龄相仿(平均54.6岁)之男性随机抽取55名非COLD亦无心脏传导异常的患者作对照。对两组病
ECG can sensitively reflect chronic obstructive pulmonary disease (COLD) and emphysema. Roughly include the change of vector and amplitude. Over the years, the author has noticed in the clinical work of patients with COLD ECG QRS time-limit has a tendency to shorten, but there are no such data reported throughout the literature. The authors randomized 55 men with non-COLD nor cardiac conduction abnormalities in a random sample of 55 men with COLD (mean age 58.9 years, confirmed by clinical, radiographic and pulmonary function tests) and similar age (mean 54.6 years) As a control. The two groups of diseases
