pressure (the second and lowest number) is the lowest pressure the
blood places on the walls of your blood vessels when the heart is
relaxed between beats.
Both of these measurements are important. A high systolic pressure
indicates strain on the blood vessels when the heart is attempting
to pump blood into your bloodstream. If your diastolic pressure is
high, it means that your blood vessels have little chance to relax
Occasional high blood pressure is common. Anxiety, exercise, or
nervousness can cause you to have a high reading (seeing a nurse
or physician for the first time can cause this response).
Untreated sustained high blood pressure can increase your risk of
premature strokes and heart attacks. If your blood pressure is
140/90* or higher, you will be asked to return for a recheck at
your earliest convenience. If your blood pressure remains high,
you will be referred to a physician for treatment.
