心脏房室大小和大血管径线的测量在器质性心脏病的诊断和鉴别诊断方面占有重要地位。以往主要依靠心脏普通X线测量,但其敏感度和准确性尚嫌不足。最精确的方法是X线心血管造影和放射性同位素(碘~(131)白蛋白)法,但必须通过心导管术,难以常规应用。近些年来,心脏超声测量技术有了较大的进展。经过X线心血管造影对比研究证明,借助于超声心动图检查,采用经过改进的、标准化的探查方法,进行左右心室、左房大小、主动脉根宽度和左室后壁厚度测量,不仅是可行的,而且可以
Measurement of cardiac atrioventricular size and large vascular diameter plays an important role in the diagnosis and differential diagnosis of structural heart disease. In the past mainly rely on the heart of the ordinary X-ray measurement, but its sensitivity and accuracy is still not enough. The most accurate method is X-ray angiography and radioisotope (iodine ~ (131) albumin) method, but must be done by cardiac catheterization, it is difficult to routinely use. In recent years, cardiac ultrasound measurement technology has made great progress. Comparative studies with X-ray angiography have demonstrated that with the aid of echocardiography, measurements of left and right ventricular, left atrial size, aortic root width, and left ventricular posterior wall thickness using an improved, standardized probing approach are not only feasible And, yes
