In many homes, blood pressure monitoring and measuring has become necessary so as to not have to go to the hospital or clinic ever so often to have it checked. Medisana BU A50 allows you to easily monitor and measure your blood pressure from your upper arm. The device displays your heart rate, systolic pressure, diastolic pressure as well as the date and time for future references – in an extra large, easy to read display. It also calculates the average of the last three measurements. Medisana BU A50 has 60 memory spaces that can be used by four difference users. The device is also able to detect heart rhythm abnormalities for the user’s prompt action.
