This
classification equates with that
of the European Society of
Hypertension (ESH) and that of
World Health Organization/
International Society of
Hypertension (WHO/ISH), and is
based on clinic blood pressure
values. If systolic blood
pressure and diastolic blood
pressure fall into different
categories, the higher value
should be taken for
classification.
