多普勒组织成像技术(Doppler tissue i maging,DTI)是近年来发展起来的一项探测心肌室壁运动的新技术,为定量分析心肌运动及功能提供了新的方法。应用DTI检测1组老年人的二尖瓣环运动速度,探讨DTI评价老年人左室舒张功能的临床应用价值。1资料与方法1.1研究对象老年组49例,男性
Doppler tissue imaging (DTI) is a new technique developed in recent years to detect myocardial wall motion and provides a new method for quantitative analysis of myocardial motion and function. DTI was used to detect mitral annulus velocities in a group of elderly patients and the clinical value of DTI in evaluating left ventricular diastolic function in the elderly. 1 Materials and Methods 1.1 Study The elderly group of 49 patients, male
