现综述正常心脏应变率成像表现和局部心肌缺血的特征;应变率成像定量评价局部收缩和舒张功能的可靠性;以及应变率成像结合负荷试验鉴别心肌不同存活状态等方面问题。
The features of normal heart rate imaging and local myocardial ischemia are reviewed. The reliability of local systolic and diastolic function is evaluated quantitatively by strain rate imaging. The strain rate imaging and load test are used to identify the different survival states of myocardium.
