Abstract

We present an algorithm for obtaining the heart rate from the signal of a single, contact-less sensor recording the mechanical activity of the heart. This vital parameter is required on a beat-to-beat basis for applications in sleep analysis and heart failure disease management. Our approach bundles information from various sources for first robust estimates. These estimates are further refined in a second step. An unambiguous comparison with the ECG RR-intervals taken as reference is possible for 98.5% of the heart beats. In these cases, a mean absolute error of 17 ms for the inter-beat interval lengths has been achieved, over a test corpus of 20 whole nights.

摘要

我们提出了一种从记录心脏机械活动的单个非接触式传感器信号中获取心率的算法。在睡眠分析和心力衰竭疾病管理的应用中，逐搏获取这一重要参数是必要的。我们的方法整合了来自各种来源的信息以进行初步的可靠估计。这些估计在第二步中进一步优化。对于98.5%的心跳，可以与作为参考的心电图RR间期进行明确比较。在20个整晚的测试样本中，这些情况下的心跳间隔长度平均绝对误差达到了17毫秒。
