in the arteries occurring when the heart contracts. The lower
reading (diastolic pressure) shows the lowest pressure in the
arteries, which occurs right before the heart contracts. Blood
pressure readings are written with the highest value first, then the
lowest value. Readings of 120/80 are considered to be normal, with
high blood pressure being defined as a systolic pressure which is
140mmHg or more at rest and a diastolic pressure which is 90mmHg
or more at rest. Only a patient's physician is qualified to determine
whether the readings obtained are normal for that person.
