Additionally, triplicate sitting Clinic Blood Pressure measurements, with one-minute interval, will be performed with the Microlife WatchBP Home-Nocturnal device during each patient's visit at the Hypertension Center. Patients will visit Hypertension Center three times, one to apply the ABPM device and one to remove it and provide the Microlife WatchBP Home-Nocturnal device and another one to bring it back. This will take approximately two weeks.
