The lower value (diastole) corresponds to the pressure that we have in the arteries between two heart beats. The upper value (systole) is the maximum pressure that is recorded in the artery in consequence of the heartbeat. In blood vessels there must be a certain pressure in order that the blood can properly flow. Each heartbeat causes a pressure wave that is transferred to the arteries. Therefore, it is necessary to properly evaluate the pressure and its variability through a pressure and heart beat digital meter.
