Objective
Despite the comparability of both methods in majority of cases (ESH 2021), physicians do not trust their patients to measure their BP correctly. The aim of this study was to ascertain that the BP measurements (BPM) are consistent and reliable.

Design and method
We enrolled 144 treated patients with essential hypertension aged 24-85 years (60% males) - all considered by their physicians as well controlled. The therapy was not changed during this study.
Mean week cycle systolic BP (SBP) of HBPTM (BP monitor Fora P30+, mobile phone for data transfer) at the beginning and end of 3 months study (triplets of BPM in morning and evening) and mean SBP of ABPMD (SEIVA TonoTrack) were compared. The required 5 minutes of physical inactivity before BPM were checked in by Xiaomi MiBand 2 smart wristbands. BP and HR values were accessible to patients and their physicians on a secure server. The data were evaluated using a linear mixed model.

Results
The values of SBP in both HBPTM and ABPMD remained steady during the trial.
The mean SBP of ABPMD was consistently higher by approximately 3 mmHg compared to the mean SBP of HBPTM both at the beginning (134.5±10.6 vs. 130.7±9.4 mmHg) and the end (133.0±11.0 vs. 129.7±10.6 mmHg), p<0.001.
Diani telemedicine system enables recording of all BPM with the marked insufficient rest before BPM, a calculation of week total, morning and evening mean BP with export of logbook in pdf, a day profile with BPM each hour to detect hypotension. It is easy to browse through week cycles of HBMTM, to record patient troubles and therapy changes. The system reports occurrence of arrhythmia by e-mail and voice evaluation of actual BPM.

Conclusions
Our results suggest that HBPTM is comparable to ABPMD. HBPTM is suitable for long-term BP follow-up and is technically sound. Questions around regulations and financing remain to be resolved.
