The Systolic number is the force of the blood on the artery walls as the heart contracts. The Diastolic is the pressure when the heart is resting in between beats. The mmhg is how the pressure is measured, which is in millimeters of Mercury.
The upper reading is the systolic blood pressure while the lower reading is the diastolic blood pressure. Systole is the contraction of the heart while diastole is the relaxation of the heart.

Pre-hypertension is when you blood pressure reading for consecutive monitoring has been within the borderline limit of hypertension and normal.
Millimetres of mercury (mmHg)
Pre-hypertension is when your blood pressure is between 120/80 mmHg and 139/89 mmHg. You do not have high blood pressure but are considered at risk for hypertension.
mmHg is a unit measuring pressure. 1mmHg=133.32Pa
You can find out if you have high blood pressure by having your blood pressure checked regularly. Most doctors will diagnose a person with high blood pressure on the basis of two or more readings, taken on several occasions. A consistent blood pressure reading of 140/90 mmHg or higher is considered high blood pressure, another term for hypertension.
Typical human blood pressure is 120/80, or 120 mmHg systolic pressure/80 mmHg diastolic pressure.
Blood pressure is the measure of the force of the blood against the walls of the blood vessels that it is contained in. Blood pressure is usually expressed in mmHg as the systolic pressure divided by the diastolic pressure.
The 115 is at the moment of contraction [beat] the 75 is the pressure between beats.
