超声心动图是一种新的无创伤性检查方法,目前已成为心血管内外科重要的诊断工具。以超声心动图评价心脏功能是最近发展起来的新技术,是心脏病学领域的一项重要进展。在国外,这种方法已广泛用于评定各种心脏病心功能,对估计病情及预后,指导治疗均有较大价值。并可用于心血管生理、药理及病理等基础研究。一、评价: 通常评价心脏功能是插入心导管测定心内压及心输出量,而测定心腔大小则须行心室
Echocardiography is a new noninvasive method of examination that has now become an important diagnostic tool for cardiovascular surgery. Echocardiographic evaluation of cardiac function is a newly developed new technology and is an important advance in the field of cardiology. Abroad, this method has been widely used to assess a variety of heart disease heart function, the prognosis of the disease and prognosis, guidance and treatment have greater value. And can be used for cardiovascular physiology, pharmacology and pathology and other basic research. First, the evaluation: Usually assess the function of the heart is inserted into the heart catheterization of cardiac pressure and cardiac output, while the determination of the size of the heart chamber must be line ventricular
