Blood pressure is a key vital sign indicating the force of blood pushing against the walls of your arteries. Understanding your systolic and diastolic numbers is critical for preventing cardiovascular disease and stroke.
Systolic vs. Diastolic Pressure
Blood pressure readings consist of two numbers. The top number (systolic) measures the pressure in your arteries when your heart beats. The bottom number (diastolic) measures the pressure in your arteries between heartbeats.
Blood Pressure Categories
According to the American Heart Association, normal blood pressure is below 120/80 mm Hg. Readings above this indicate elevated blood pressure or hypertension. You can check and categorize your blood pressure readings instantly using our interactive Blood Pressure Checker.
