Blood pressure as a main factor in the diagnostic of arterial hyperten
sion is subject to a strong variability and this determines that the o
ccasional blood pressure measurement can lead to diagnostic and progno
stic mistakes. The ABPM as well as the ergometry can clearly improve t
he estimation. This succeeds in the case of high blood pressure diagno
sis by ergometry, in which is tested ifa proband can decrease the peri
pheral vascular resistance during the standardized dynamic burden and
during the ABPM through increase of density in the measured value unde
r everyday conditions. For both procedures the following is valid: the
y are based on dependable normal values and the data show good reprodu
cibility; a white smock hypertension can be reliablely recognized; the
re is in contrast to occasional blood pressure measurement better evid
ence as far as cardiovascular complications are concerned; through the
avoidance of placebo effects and exagerrated therapy as well as contr
ol of the effective length the dependability of therapy is increased.
