摘要

背景:反射波到达中央动脉的时间对心室后负荷有重要影响。目前估计反射时间(RT)的方法，包括零交叉[1]、拐点[2]和足部[3]方法，仅使用压力波形上的单点，由于没有地面真实反射时间(GTRT)可用，其精度不确定。本文介绍了一种新的质心方法，该方法考虑了整个波形，并首次将RT方法的精度与GTRT方法进行了比较。

P.05 Development and Validation of a Novel Centroid Method for Estimating Effective Reflection Time

Background: The time at which reflected waves arrive at central arteries has an important influence on ventricular afterload. Current methods of estimating reflection time (RT), including zero-crossover [1], inflection-point [2], and foot methods [3], use only a single point on the pressure waveforms, and their accuracy is uncertain because no ground truth reflection time (GTRT) has been available. We here introduce a novel centroid method that accounts for the entire waveform and compare the accuracy of RT methods by comparison with a GTRT for the first time.
