What do the two numbers in a blood pressure reading mean?
The first (or top) number of your blood pressure reading is called the “Systolic” blood pressure. (For example, if your blood pressure is 146/86, then your systolic blood pressure is 146.) The second (or bottom) number of your blood pressure reading is called the “Diastolic” pressure. (For example, if your blood pressure is 146/86, then your diastolic blood pressure is 86.
