In recent years cardiac electrocardiograms and electrograms often have been measured using automated sampling systems that record samples periodically, with a fixed sample-to-sample interval. In contrast, adaptive sampling systems envision variable sample-to-sample intervals, and new information about such systems has emerged in the last few years. The author summarizes these reports. On the whole, they show that the fan algorithm is an effective basis for adaptive sampling of cardiac waveforms, that it works well on electrocardiograms, electrograms, and action potentials, and that prototype sampling systems based on the fan can be constructed to run in real time.
近年来，心电图和心电描记图常常使用自动采样系统进行测量，这些系统以固定的采样间隔定期记录样本。相比之下，自适应采样系统设想的是可变的采样间隔，并且在过去几年中出现了关于此类系统的新信息。作者总结了这些报告。总体而言，它们表明扇形算法是心脏波形自适应采样的有效基础，在心电图、心电描记图和动作电位方面都能很好地发挥作用，并且可以构建基于扇形算法的原型采样系统以实时运行。
