Understanding your blood pressure reading
Blood pressure is measured in millimetres of mercury (mmHg) and is given as two figures:

  • Systolic pressure – the pressure when your heart pushes blood out.
  • Diastolic pressure – the pressure when your heart rests between beats.

For example, if your blood pressure is ``140 over 90`` or 140/90mmHg, it means you have a systolic pressure of 140mmHg and a diastolic pressure of 90mmHg.
