Sustained high blood pressure is known as hypertension.
Blood pressure is the pressure of the blood on the walls of the vessels.
Normal BP is 120/80 mmhg
In Hypertension BP > 130/90

         i.          Grade 1 hypertension: Also called Mild hypertension

Systolic BP = 130-140 mmhg          Diastolic BP = 85-90 mmhg
       ii.           Grade 2 hypertension: Also called Moderate hypertension

Systolic BP = 140-160 mmhg          Diastolic BP = 90-95 mmhg
      iii.           Grade 3 hypertension: Also called Severe hypertension
Systolic BP = 160-180 mmhg          Diastolic BP = 95-100 mmhg
     iv.            Grade 4 hypertension: Also called Malignant hypertension
Systolic BP >180mmhg          Diastolic BP > 110mmhg
