超声心动图评价右室扭转的一种新的数学/数值公式
A Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging
摘要：
近年来，心室扭转参数因其在心室收缩和舒张功能中的重要作用而受到特别的关注。右心室旋转变形是反映右心室功能的敏感指标，但测量困难。假设RV为圆锥形，本研究提供了一种新的右心室旋转的数学公式，使用速度矢量成像（VVI）量化RV。
英文摘要：
Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure. Having assumed RV as a conic shape, the present study serves a novel mathematical formula of right ventricular rotation that uses velocity vector imaging (VVI) for quantifying RV.
