Pulsed Doppler (PW) and tissue Doppler imaging (TDI) measurements are part of every echocardiography examination for evaluation of left ventricular (LV) diastolic function and filling pressure. The purpose of this study was to summarize published data on normal values for PW and TDI measurements. A PubMed search was performed on the 10th of October 2016 to identify relevant articles. Studies were considered relevant if they included more than 200 healthy individuals. A total of 13 studies were identified. Of these, 13 studies with 7777 subjects reported PW measurement over the mitral valve, six studies with 4082 subjects reported PW measurement in the pulmonary vein and 10 studies with 5988 subjects reported TDI. We also report weighted mean values for 14 different variables. As expected, measurements varied with age. There were no major differences between men and women. In contrast, there was a large difference in reported values between studies, in corresponding age groups. This review therefore raises caution about relying on normal values from just one study.
脉冲多普勒（PW）和组织多普勒成像（TDI）测量是每次超声心动图检查中评估左心室（LV）舒张功能和充盈压的一部分。本研究的目的是总结已发表的关于PW和TDI测量正常值的数据。2016年10月10日在PubMed上进行了检索，以识别相关文章。如果研究纳入了超过200名健康个体，则被认为是相关的。共识别出13项研究。其中，13项研究共7777名受试者报告了二尖瓣PW测量值，6项研究共4082名受试者报告了肺静脉PW测量值，10项研究共5988名受试者报告了TDI测量值。我们还报告了14个不同变量的加权平均值。正如预期的那样，测量值随年龄而变化。男性和女性之间没有重大差异。相比之下，在相应年龄组中，不同研究报告的值存在很大差异。因此，本综述提醒人们谨慎依赖仅一项研究的正常值。
