AIM: To investigate the relation between left ventricular torsion(LVtor)/ rotation and cardiac cycle in normal persons by speckle tracking imaging(STI).

目的:探讨斑点追踪显像技术(STI)评价正常人心肌旋转及左室扭转与心动周期时相关系的价值。

IntroductionLeft ventricular torsion(LVT)is defined as the left ventricular torsional deformation of apical counterclockwise rotation and basal clockwise rotation viewed from apex,of which the value calculated by the difference between apical rotation(AR) and basal rotation(BR).

前言左室扭转(left ventricular torsion,LVT)指由心尖向心底观察收缩期心尖逆时针旋转与心底顺时针旋转形成的左室扭转运动,其大小等于心尖旋转减心底旋转。
