Information for patients: Systolic high blood pressure
Blood pressure is typically recorded as two numbers — the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats).

The diastolic does not need to be high for you to have high blood pressure. When that happens, the condition is called "isolated systolic hypertension," or ISH.  more
