Blood pressure measurement is inexpensive and easily performed.
Blood pressure is measured in two phases that correspond to the
natural contractions of the heart. When the heart contracts
(e.g., systole), the pressure of blood against arterial walls
is known as systolic pressure.
When it relaxes (diastole), the pressure of blood against arterial
walls is known as diastolic pressure.
