Consideration of Calculation Process Assuming Heart Rate Variability Analysis Using Wearable ECG Devices.

Abstract

Since many shirt-type wearable electrocardiogram (ECG) devices employ shirt-embedded dry electrodes that are easily affected by the daily activities of users, measured ECG often includes noise or artifacts. Experiments confirmed that a desirable HRV calculation process assuming these wearable ECG devices is a combination of accurate R wave detection, RRI outlier exclusion and missing RRI complement methods.
