| 中文摘要: |
| 左心室松弛时间常数(Tau)是公认的、测量左心室舒张功能的最好指标。美国超声心动图学会(ASE)的舒张功能指导大纲(2009)推荐了两个无创测算的计算公式,但临床未得到应用。本文详细分析了以上两个无创测算方法及其弊端,并介绍了一组新的计算公式,分析了新公式可能存在的问题及解决方案。 |
| 英文摘要: |
| Left ventricular diastolic time constant, Tau is the most established index to describe left ventricular diastolic function. The American Society of Echocardiography (ASE) Diastolic Function guideline (2009) recommends two methods for its non-invasive calculation. However, few clinicians are using them. Those two methods were investigated and the flaws were analyzed in this review. A new set of formulas was introduced and the new possible problems and solutions were addressed. |
