心率变异性（HRV）是心电图（ECG）上连续R波之间的间隔变化的指标，称为R-R间期（RRI），由自主神经系统活动引起。RRI的测量可用于检测与自主神经系统活动相关的疾病和预测癫痫发作。本研究提出了一种改进的心率测量系统，该系统将高度准确，紧凑，廉价的贴片式RRI遥测仪与智能手机应用程序相结合，无需专家即可自动选择适当的测量位置。为了评估测量的准确性，10名健康男性和10名健康女性在仰卧位，坐着，站着，步行（3公里/小时）的姿势，同时使用该系统和参考心电图测量系统测量RRI，并得到的结果进行了比较。此外，测量R波的检出率，并进行Bland-Altman分析，以分析所提出的系统的测量精度。结果表明，R波检测率和协议的限制是足够准确的HRV分析的68和67的总的80个时期，分别。该系统有望提高非专家进行ECG测量的能力，并将有助于通过在家连续监测来提高医疗质量。
Heart rate variability (HRV) is an indicator of changes in the interval between successive R-waves on the electrocardiogram (ECG), known as R–R intervals (RRI), caused by autonomic nervous system activity. Measurement of RRI is useful in detecting diseases related to autonomic nervous system activity and predicting seizures. This study proposes an improved heart-rate measurement system that combines a highly accurate, compact, and inexpensive patch-type RRI telemeter with a smartphone application that automatically selects the appropriate measurement position without the need of an expert. To evaluate the measurement accuracy, the RRIs of 10 healthy men and 10 healthy women in supine, sitting, standing, and walking (3 km/h) postures were simultaneously measured using the proposed system and a reference ECG measurement system, and the obtained results were compared. Furthermore, the R-wave detection rate was measured, and Bland–Altman analysis was conducted to analyze the measurement accuracy of the proposed system. The results show that the R-wave detection rate and limit-of-agreement were sufficiently accurate for HRV analysis for 68 and 67 out of the total of 80 epochs, respectively. The fabricated system is expected to enhance the ability of non-experts to conduct ECG measurements and will contribute to improve the quality of healthcare through continuous monitoring at home.
