The top number measures the pressure in the arteries when the heart beats. Bottom number, called diastolic pressure. The bottom number measures the pressure in the arteries between heartbeats. The American College of Cardiology and the American Heart Association divide blood pressure into four general categories.
Systolic (the number on top): pressure exerted when the heart pumps blood throughout the body. Diastolic (the number at the bottom): pressure exerted when the heart relaxes and refills with blood. When your blood pressure is consistently higher than 130/80 mm Hg, you are considered to have hypertension.

Systolic blood pressure is the top number and refers to the amount of pressure experienced by the arteries while the heart is beating. Diastolic blood pressure is the bottom number and refers to the amount of pressure in the arteries while the heart is resting in between heartbeats.
Systolic (top): This measures the pressure of your blood on the artery walls as your heart beats. Diastolic (bottom): This measures the pressure when your heart rests between beats. Keep reading...
If your top number is under 90 or your bottom number is under 60, you may be diagnosed with low blood pressure. Use the chart to see where your numbers sit. If your top number (systolic pressure) is consistently higher than 140mmHg, but the bottom number is healthy - this is known as Isolated Systolic Hypertension.
