For many years, the echocardiographic quantitative assessment of right ventricular (RV) function has been difficult owing to the complex RV anatomy. Identifying an accurate and reliable echocardiographic parameter for the functional assessment of the RV still remains a challenge. The review presents a summary of the most studied and presently used parameters of RV function, with their reported normal values, as well as advantages and limitations of use. Combinations of these parameters are used in daily clinical practice, each one offering only partial information about the status of the RV. Myocardial velocity and strain rate imaging have promising results in the assessment of RV function. There is hope that novel myocardial deformation parameters and three-dimensional echocardiography-derived parameters may add value to the examination of the RV, but validation studies are still needed.
多年来，由于右心室（RV）解剖结构复杂，对其功能进行超声心动图定量评估一直很困难。确定一个准确可靠的用于RV功能评估的超声心动图参数仍然是一项挑战。本文综述了目前研究最多且常用的RV功能参数，包括其报告的正常数值，以及使用的优点和局限性。这些参数的组合在日常临床实践中使用，每个参数仅提供关于RV状态的部分信息。心肌速度和应变率成像在RV功能评估中取得了有前景的结果。有望新型心肌变形参数和三维超声心动图衍生参数可为RV检查增添价值，但仍需进行验证研究。
