What do the two different blood pressure numbers mean?
The gold standard for blood pressure is for it to be less than 120/80. The top (or first) number, in this case 120, is the systolic pressure. It’s the measurement of how hard the heart is contracting when it beats. The lower (or second) number, in this case 80, is the diastolic pressure. It’s the measurement of the heart relaxing after it contracts.
