Using wearables to measure HRV

The validity of HRV results using wearables has been questioned in academia. Wearable devices usually adopt photoplethysmography (PPG), using the photo sensors in the device, rather than electrocardiograph (ECG) that is used in medical and strap based heart rate monitors (HRM), to measure HRV. The top wearable devices use algorithms to compensate for the inaccuracies… Continue reading Using wearables to measure HRV

Heart Rate Variability: From Standard ECG Monitors to Wearables

Evangelia AthanasiouiMotions Product Management AssistantAugust 31st, 2021 Original at: https://imotions.com/blog/heart-rate-variability-ecg-wearables/ Monitoring Heart Rate Variability (HRV) allows for exploring human activity through the heart, which can help us gain insight into health issues and behaviors. For example, fatigue and stress are daily characteristics that we can obtain by measuring¬†HRV. In general, low HRV data can indicate… Continue reading Heart Rate Variability: From Standard ECG Monitors to Wearables
