This is an example of a person using a home blood pressure meter. Blood pressure is explained with 2 numbers. For instance, your blood pressure might be "140 over 90." The "systolic" (first) number is the pressure inside your arteries when your heart is contracting. The "diastolic" (second) number is the pressure inside your arteries when your heart is relaxed. Most home blood pressure monitors also show your pulse. Your pulse is the number of times your heart beats in 1 minute.
