Regional myocardium function in rabbit with acute myocardial ischemia assessed by velocity vector imaging
速度向量成像技术评价兔急性心肌缺血局部心肌功能的研究

Objective To utilize velocity vector imaging (VVI) in analyzing regional myocardium function within 30 minutes before and after myocardial ischemia induced by occlusion of coronary artery in New Zealand white rabbits and to evaluate the changes of longitudinal and brachydiagonal segmental left ventricular(LV) systolic function in rabbits with acute myocardial ischemia. Methods Thirty New Zealand white rabbits were divided into groups of myocardial ischemia and sham operation. All rabbits were performed by e...
