heart’s «rest period» (Diastole) minimal (diastolic blood-pressure value). The blood-pressure
values must lie within certain normal ranges in order to prevent particular diseases.
2.2 Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg and/or the systolic
blood-pressure is over 140 mmHg. In this case, please consult your doctor immediately. Long-
term values at this level endanger your health due to the associated advancing damage to the
blood vessels in your body.
With blood-pressure values that are too low, i.e. systolic values under 100 mmHg and/or diastolic
values under 60 mmHg, likewise, please consult your doctor.
Even with normal blood-pressure values, a regular self-check with your blood-pressure monitor is re-
commended. In this way you can detect possible changes in your values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, please keep a record of
the level of your blood pressure by carrying out regular self-measurements at specific times of
the day. Show these values to your doctor. Never use the results of your measurements to
alter independently the drug doses prescribed by your doctor.

☞ Further information
• If your values are mostly standard under resting conditions but exceptionally high under con-
ditions of physical or psychological stress, it is possible that you are suffering from so-called
«labile hypertension». Please consult your doctor if you suspect that this might be the case.
• Correctly measured diastolic blood-pressure values above 120 mmHg require immediate
medical treatment.
