A non-invasive technique such as echocardiography has numerous advantages over invasive examinations of the cardiovascular system. Echocardiography involves no hazard or risk to the health of the patient, it can be repeated at any time and provides truly basal haemodynamic information by avoiding sedation, excitation of the patient and injection of dye. Problems arising from peculiarities in the behavior of ultrasonic energy and chest malformations in the patient have been largely overcome by technical improvements and a more sophisticated wasy of examination. The current diagnostic applications of echocardiography are reviewed on the basis of our own experience and the advantages and limitations of this method discussed.
像超声心动图这样的非侵入性技术相对于心血管系统的侵入性检查有许多优势。超声心动图对患者健康没有危害或风险，它可以在任何时候重复进行，并且通过避免患者镇静、兴奋和注射染料来提供真正的基础血流动力学信息。超声能量行为的特殊性和患者胸部畸形所产生的问题已通过技术改进和更复杂的检查方法得到了很大程度的克服。基于我们自己的经验对超声心动图目前的诊断应用进行了综述，并讨论了该方法的优缺点。
