心室扭转与心室纤维排列的关系
Ventricular torsional relation to ventricular fiber arrangement
摘要：
由螺旋定向肌纤维引起的左心室扭转是心脏性能的关键参数。在超声心动图上、在心导管插入术期间或在手术室中观察心脏运动的医生对收缩期间左心室的扭转或旋转运动印象深刻。从概念上讲，心脏被视为一个压力室。基础科学家对旋转或扭转变形了解甚少，缺乏临床相关性。本文旨在探讨：心室扭转是否与心室纤维排列有关？这取决于左心室结构的假设模型。
英文摘要：
Left ventricular torsion from helically oriented myofibers is a key parameter of cardiac performance. Physicians observing heart motion on echocardiograms, during cardiac catheterization, or in the operating room, are impressed by the twisting or rotary motion of the left ventricle during systole. Conceptually, the heart has been treated as a pressure chamber. The rotary or torsional deformation has been poorly understood by basic scientists and has lacked clinical relevance. The aim of this paper attempts to discuss about this question: Is ventricular twisting related to ventricular fiber arrangement? That is dependent to an assumed model of the left ventricular structure.
