Abstract
Hypertension is defined as systolic arterial pressure greater than or equal to 160 mmHg and/or diastolic arterial pressure greater than 95 mmHg measured in the sitting position under quiet conditions at least on two occasions (WHO). If there is any doubt noninvasive ambulatory blood pressure (Holter) can be measured.
