The field of ballistocardiography seems to be enjoying a recent resurgence, most notably through the development of novel technologies and signal processing methods for measurement and analysis. After the method almost vanished in the late 80's and 90's, it is reasonable to wonder what is different this time, and if the technique has now more chances of becoming what its pioneer always wanted - a widespread clinical tool. This paper is an effort to compare and contrast this novel wave of research (notably in the context of the authors' own work). It also suggests that the new approaches have several key differences with past embodiments that place them in a good position to address some specific issues such as cardiac resynchronization therapy device optimization or congestive heart failure monitoring. This optimism is largely fed by the recent technological advances enabling the measurement of the BCG unobtrusively, frequently, at home or in a hospital, and by a re-focus on monitoring and trending applications.
心冲击图领域似乎最近正在复兴，最显著的是通过开发用于测量和分析的新技术及信号处理方法。在该方法于80年代末和90年代几乎消失之后，很自然会想这次有何不同，以及该技术现在是否更有机会成为其先驱一直期望的——一种广泛应用的临床工具。本文旨在比较和对比这一波新的研究浪潮（特别是结合作者自身的工作背景）。文章还指出，新方法与过去的实施方案有几个关键差异，这使它们有很好的条件来解决一些特定问题，如心脏再同步治疗设备优化或充血性心力衰竭监测。这种乐观情绪很大程度上源于近期的技术进步，这些进步使得能够在家中或医院以不显眼且频繁的方式测量心冲击图，还源于对监测和趋势应用的重新关注。
