Blood pressure monitor's number SYS..102.... DIA...45...PUL.85.. What's the meaning of the number?

Sys (systolic) is the blood pressure in your arteries when the heart is actually beating; Dia (diastolic) is the blood pressure in your arteries in between the heart beats; Pul (pulse) is the number of times the heart beats in one minute. Those blood pressure readings are below normal so get checked out by a doctor if you are not already.
