The tendency of the heart to contract is the main cause of blood pressure. There are two types of blood pressure. High or high blood pressure and low or low blood pressure. High blood pressure is known as systolic pressure and low blood pressure known as diastolic blood pressure.
Blood pressure is an important symptom like heart rate, heart rate, body temperature. The normal steady blood pressure of an adult is about 120 mmHg systolic and 60 mmHg is diastolic. In short, 120/80 mmHg.
High blood pressure (Systolic):
High or systolic blood pressure is measured by the force our heart exerts on the walls of our arteries each time it beats.
Normal: Below 120 mmHg
Elevated: 120-129 mmHg
Stage 1 High blood pressure (also called hypertension): 130-139 mmHg
Stage 2 Hypertension: 140 mmHg or more
Hypertensive crisis: 180 mmHg or more. Call emergency immediately
Low blood pressure (diastolic)
Low blood pressure or diastolic blood pressure is measured by the pressure on the walls of our arteries between heartbeats.
Normal: Lower than 80 mmHg
Stage 1 hypertension: 80-89 mmHg
Stage 2 hypertension: 90 mmHg or more
Hypertensive crisis: 120 mmHg or more. Call emergency immediately
