Many new approaches towards noninvasive cardiology have been introduced into clinical practice recently and "old" methods such as apexcardiography reevaluated. Problems concerning calibration of some of these systems will be discussed briefly. Advances have been made recently in the field of optical methods: chest wall displacement can be obtained using light sources (Moiré interferograms and laser displacement). Combination of different methods: echo-, phono- and mechanocardiography, have led to completely new insights in the genesis of low frequency and high frequency vibrations of the heart. Digital signal processing methods have been developed for the analysis of combined echo-phono-mechanocardiograms. In this way left ventricular function can be determined in a very effective way.
最近，许多无创心脏病学的新方法已被引入临床实践，同时对诸如心尖心动图等“旧”方法也进行了重新评估。将简要讨论其中一些系统的校准问题。光学方法领域最近取得了进展：可以使用光源（莫尔干涉图和激光位移）来获取胸壁位移。不同方法的结合，如超声心动图、心音图和机械心动图，已在心脏低频和高频振动的发生机制方面带来了全新的见解。已经开发出数字信号处理方法用于分析联合超声心动图 - 心音图 - 机械心动图。通过这种方式，可以非常有效地确定左心室功能。
