可穿戴ECG设备捕获的心电图（ECG）由于测量故障而容易包含伪影。由于伪影的频率特性与R波的频率特性非常相似，因此可能导致R-R间期（RRI）的误计算。为了在日常生活中进行准确的心率变异性（HRV）分析，本文提出了一种可靠地评估RRI测量状态的方法，该方法使用QRS波群的电位特性。初步评估结果表明，它有可能区分计算错误的RRI。还提出了一种新的RRI离群排除方法，使用上述方法。时域测量的HRV来自建议的RRI离群排除方法被发现是更准确的比那些来自传统的。
Electrocardiograms (ECGs) captured by wearable ECG devices easily contain artifacts because of measurement faults. Since the frequency characteristics of artifacts are quite similar to those of R waves, it may result in R-R interval (RRI) miscalculations. To enable accurate heart rate variability (HRV) analysis in daily life, this paper proposes a method to reliably evaluate RRI measurement status, one that uses the electric potential characteristics of the QRS complex. Initial evaluation results show that it has the potential to distinguish miscalculated RRIs. Also proposed is a new RRI outlier exclusion method that uses the aforementioned method. Time domain measures of HRV derived from the proposed RRI outlier exclusion method are found to be more accurate than those derived from the conventional one.
