斑点追踪技术在心律失常中的应用进展

Application progress of speckle tracking echocardiography in arrhythmia

我国目前心律失常发病率快速上升,呈年轻化和不断增长的趋势,常引起心力衰竭、心源性休克、脑血栓等危重症的发生。心律失常往往伴有心肌结构及功能的变化,评估心律失常患者整体及局部心肌功能对患者治疗方案选择、治疗效果评估及远期治疗结局预测有重要的意义。斑点追踪技术(STE)是新近兴起的超声技术,可定量评估心肌功能,较常规超声心动图有无角度依赖性等优势,可用于识别细微心肌损伤,其单独或联合常规心脏超声在心律失常疾病的多个方面均有应用。本文就其在心律失常中的临床应用及研究进展作一综述。

At present,the incidence of arrhythmia in China is rising rapidly,showing a trend of being younger and increasing,which often causes the occurrence of critical illnesses such as heart failure,cardiogenic shock,and cerebral thrombosis.Arrhythmia is often accompanied by changes in myocardial structure and function.Evaluating the overall and partial myocardial function in patients with arrhythmia is of great significance for selection of treatment options,evaluation of treatment effect,and prediction of long-term treatment outcomes.Speckle tracking echocardiography(STE)is a newly emerging ultrasound technology that can quantitatively assess myocardial function,which has no angle-dependent advantage over conventional echocardiography,can be used to identify subtle myocardial damage,and has applications in multiple aspects of arrhythmia disease alone or in combination with conventional echocardiography.This article reviews its clinical application and research progress in arrhythmia.
