High blood pressure (hypertension) - Symptoms and causes
Hypertension can be diagnosed by performing careful and repeated measures of the blood pressure. Blood pressure categories include normal blood pressure, defined as a systolic pressure less than 120, and a diastolic pressure less than 80. Elevated blood pressure is defined as a systolic pressure 120 to 129, and a diastolic pressure less than 80.
Isolated systolic hypertension: A health concern? - Mayo Clinic
