What Does The Diastolic Blood Pressure Measurement Mean?
While the systolic (upper number in the fraction) pressure represents the pressure on your arteries as your heart contracts and pushes blood poured into your arteries, the diastolic pressure is the pressure that is present in your arteries after the contraction has happened and the heart has relaxed. In other words, with every beat of your heart, you have one number that represents pressure in your arteries during the contraction (systolic) and one number that represents the pressure on your arteries after the contraction (diastolic).
