多数标准教课书曾描述,如果心尖搏动位于左第五肋间锁骨中线外或心尖搏动距前正中线水平距离超过10cm,即可诊断心脏肥大。然而,迄今众多临床医师对此持怀疑态度.据此,本文对心脏肥大的物理诊断之准确性作一评价。对象与方法:对象为100例住院病人(男64,女36),均摄有胸部正位X线片。由两位观察者分别进行体检,先确定心尖搏动在左侧肋间隙及锁骨中线内外的位置,然后测量其距前正中线的水平距离(cm).当病人半卧位或前倾坐位并嘱呼气末 Most standard textbooks have described cardiac hypertrophy if the apical beating is outside the midline of the left fifth intercostal clavicle or when the apical beating distance is more than 10 cm from the anterior midline. However, so far many clinicians are skeptical.Therefore, this article to assess the accuracy of the physical diagnosis of cardiac hypertrophy. Subjects and Methods: Subjects were 100 inpatients (male 64, female 36), were taken chest X-ray film. By two observers were physical examination, first determine the apical beating in the left intercostal space and the position of the medial and lateral clavicular line, and then measure the distance from the median line before the distance (cm) .When the patient semi-supine or forward sitting position and Exhale end
