多巴酚丁胺负荷超声是目前世界上广泛应用的检测冬眠心肌的有效方法,具有较高的敏感性和特异性,但其图像分析采用半定量目测法,结果的分析判断易受主观因素影响,带有较强的经验依赖性。组织多普勒是近年发展起来的一项定量分析室壁运动的超声新技术,与多巴酚丁胺负荷超声相结合可弥补其半定量目测法的不足。 Dobutamine stress ultrasound is widely used in the world to detect hibernating myocardium effective method with high sensitivity and specificity, but the image analysis using semi-quantitative visual method, the results of the analysis to determine susceptible to subjective factors , With a strong empirical dependence. Tissue Doppler was developed in recent years, a quantitative analysis of wall motion ultrasonic new technology, combined with dobutamine stress ultrasound can make up for its lack of semi-quantitative visual method.
