Evaluation of regional left ventricular systolic dysfunction in patients with infarct and ischemia myocardial by speckle tracking imaging
斑点追踪成像技术评价梗死心肌和缺血心肌对左心室局部收缩功能的影响

Objective To assess the longitudinal,radial and circumferential systolic strain (LS,RS,CS) and strain rate (LSR,RSR,CSR) from regional myocardial in patients with myocardial infarction and ischemia by speckle tracking imaging(STI) and to evaluate regional left ventricular systolic dysfunction.Methods The high frame rate two-dimensional echocardiography were performed in the 30 patients of the myocardial infarction and 25 patients of the ischemia myocardial group and 25 healthy subjects. The longitudinal and...
