Methods 25 patients with dilated cardiomyopathy and 30 healthy subjects(control group)were enrolled in this study. The 16-segments velocity、strain and strain rate curves were obtained from the standard LV apical views and the parasternal short axis(SAX)views by VVI examinations.
方法DCM患者25例和健康志愿者30例,在系列心尖长轴及胸骨旁短轴观上,VVI成像得到左室16节段速度、应变、应变率达峰时间等图像或曲线。
