"ELITE HRV" (for iOS and Android) is one of the most popular free mobile apps that is able to calculate HRV by smartphones.Purpose: The study aim was to analyse the standard time domain parameters of HRV by comparing the ECG-based vs the mobile approach. The classic approach uses an ECG and known mathematical algorithms to obtain HRV, while the mobile approach computes HRV from non-ECG signals, e.g. derived by a chest heart rate monitor (HRM) and a special mobile app.Methods: 29 healthy individuals (21-30 years old; 14 women) underwent a simultaneous acquisition of the 5-minute ECG (Porti 17, TMSI, The Netherlands) and heart rate signal...
