1. For a normal reading, your blood pressure needs to show a top number (systolic pressure) that's between 90 and less than 120 and a bottom number (diastolic pressure) that's between 60 and less than 80

A condition in which the force of the blood against the artery walls is too high.

2. Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120.
