When checking your blood pressure, your result will appear as two numbers written like a fraction: one number on top and one on the bottom. For example, "normal" blood pressure is generally read as 120/80. But what do these numbers mean?
These numbers refer to two types of blood pressure:
- Systolic pressure (the number on top) measures the pressure inside your blood vessels at the moment your heart beats
- Diastolic pressure (the number on the bottom) measures the pressure in your blood vessels between heartbeats, when your heart is resting.
