hardening of the arteries. If such conditions continue,
there is an increased danger of apoplexy and coronary
infarction, arterial stenosis and disorder in peripheral
blood circulation. In such cases, there will be a large
difference between blood pressure values taken at the
wrist and upper arm. (Since even healthy persons may
show a difference of 20 mmHg if the conditions of the
measurement status are not suitable. Do not rely on the
self-diagnosis or just one measurement, and always
follow the advice of a physician.) Physiological
conditions may have varying degrees of effect, but
generally blood pressure values at the wrist and upper
arm should display the same pattern of change.
Consequently, it is possible to monitor trends in change
by measuring blood pressure at the wrist.
