Cardiology - Cardiac Electrophysiology
In brief: Systole and Diastole
The heart is a pump.
Every time it beats, it squeezes blood out to the body. The systolic blood pressure is the pressure measurement, in mm Hg, recorded in the arteries when the heart is squeezing. This is the point when the pressure is highest. The diastolic blood pressure is the pressure recorded when the heart is relaxing and is the point when pressure lowest. (e.g. 120/80 = systolic/dias.

In brief: See below
Systolic blood pressure(top #) is the pressure measured when the heart is contacting(ejecting blood ) while diastolic pressure (bottom#) is the pressure when the heart is relaxing and filling with blood.
