traditionally been emphasized because it is less subject to fluctuations. Recent studies, including the ongoing Framingham heart study, have revealed that systolic pressure may be as significant a heart attack predictor as diastolic pressure.
Blood pressure is indicated by two numbers each referring to how in millimeters the pressure of the blood in your arteries can raise a column of mercury (Hg). The first number, the systolic pressure, represents the force of blood during the heartbeat. The second number, the diastolic, indicates the pressure between heartbeats. Here is the schedule:
