Background and Aim: Most recommendations on blood pressure (BP) measurement and hypertension have stated that BP should be measured in both arms and that the hand with the highest value should be used for subsequent measurements. It has been suggested that differences in the right and left arm pressures may be caused by undiagnosed peripheral vascular disease affecting the vasculature of upper limbs and may, therefore, predict an increased risk of cardiovascular disease. Methods: Simultaneous bilateral brachial BP measurements were taken after 10 min resting period in supine position; three BP measurements were taken simultaneously and automatically using a validated automatic oscillometric device (Microlife WatchBP office) at 1 min interval. Results: There were 22, 19, and 9 participants with interarm systolic BP difference of
