利用X线测量心脏大小有多种方式,心象(正面)面积测量是一种较为准确的方法,它可作为确定心脏是否增大的客观指标,也可作为诊断心脏疾病时的依据。常用的有Eyster和Hodges两氏作的心脏面积与横径的公式,以及Clark氏和Ungerleider氏的公式与表格。国内多采用汪、谢氏公式求得心脏面积。此后屡有报道,但所得之心脏面积正常标准仅适用于成人,对14岁以下的儿童不适用。临床多用心胸比率判定儿童及少年心脏大小,而我们在
There are many ways to measure the size of the heart by X-ray. The measurement of the area of the heart (frontal) is a more accurate method. It can be used as an objective index to determine whether the heart is enlarged, or it can be used as a basis for the diagnosis of heart disease. Commonly used Eyster and Hodges’s formula for the area and diameter of the heart, as well as Clarks and Ungerleider’s formulas and tables. Many domestic use Wang, Xie’s formula to obtain the heart area. Since then, there have been repeated reports, but the normal standard of heart area obtained applies only to adults and is not applicable to children under 14 years of age. The clinical multi-cardiac ratio is used to determine the heart size of children and teenagers, and we are
