Clinical blood pressure measurement verification when comparing a Tensoval duo control device with a mercury sphygmomanometer in patients suffering from atrial fibrillation.

Aim: The aim of our study was to compare the accuracy of blood pressure measurements in patients with atrial fibrillation using simultaneous measurements by a mercury sphygmomanometer and an electronic device Tensoval duo control, produced by Hartmann-Rico, with dual control of the measurements (oscillometric and auscultation).

Materials And Methods: A total of 255 patients were examined at five clinics using two simultaneous measurements with a time interval of at least 3 min. The measurement accuracy analysis was carried out using a paired t-test, at several levels, throughout the whole group of patients, by considering the patient's sex and age and using a standard or larger cuff.
