Dr. Jill Valerius joins Lee Henrikson to discuss high blood pressure.

Dr. Jill explains how your blood pressure is taken and when it should be taken.

The second number is your diastolic pressure, which is measured between heartbeats when the heart is filling with blood. Blood pressure can be a problem all on its own, but it can also be a symptom of other ailments.
