HeartBEAT:通过自适应跟踪进行心跳估计

HeartBEAT: Heart Beat Estimation through Adaptive Tracking

Huijie Pan, Dogancan Temel, Ghassan AlRegib

摘要:

在本文中,我们提出了一种算法表示为HeartBEAT,跟踪心率从手腕型光电容积脉搏波(PPG)信号,同时记录的三轴加速度数据。HeartBEAT包含三个主要部分:PPG信号和加速度数据的谱估计,使用递归最小二乘(RLS)自适应滤波器消除PPG信号中的运动伪影,以及辅助算法。我们在2015年IEEE信号处理杯提供的22个数据集上测试了HeartBEAT。前10个数据集记录了受试者进行前臂和上臂锻炼,跳跃或俯卧撑。最后12个数据集是从在跑步机上跑步的受试者记录的。将实验结果与来自同时记录的心电图(ECG)信号的地面真实心率进行比较。与最先进的算法相比,HeartBEAT不仅产生可比较的Pearson相关性和平均绝对误差,而且还产生更高的Spearman rho和Kendall tau。

英文摘要:

In this paper, we propose an algorithm denoted as HeartBEAT that tracks heart rate from wrist-type photoplethysmography (PPG) signals and simultaneously recorded three-axis acceleration data. HeartBEAT contains three major parts: spectrum estimation of PPG signals and acceleration data, elimination of motion artifacts in PPG signals using recursive least Square (RLS) adaptive filters, and auxiliary heuristics. We tested HeartBEAT on the 22 datasets provided in the 2015 IEEE Signal Processing Cup. The first ten datasets were recorded from subjects performing forearm and upper-arm exercises, jumping, or pushing-up. The last twelve datasets were recorded from subjects running on tread mills. The experimental results were compared to the ground truth heart rate, which comes from simultaneously recorded electrocardiogram (ECG) signals. Compared to state-of-the-art algorithms, HeartBEAT not only produces comparable Pearson's correlation and mean absolute error, but also higher Spearman's rho and Kendall's tau.
