Hypertension - essential

Alternative names
Essential hypertension

Definition

As blood is pumped through your body, it exerts pressure on the walls of your arteries. The systolic blood pressure is the pressure against these walls when the heart contracts, and the diastolic blood pressure is the pressure when the heart relaxes. When you get a blood pressure reading, you are told the systolic pressure/diastolic pressure.
