- Etiology is unknown in 90 – 95% cases.
- Greater than normal tension or tone.
2. In adults, a condition in which the blood pressure (BP) is higher than 140 mm Hg systolic or 90 mm Hg diastolic on three separate readings recorded several weeks apart.
Normal blood pressure: systolic <120 mmHg and diastolic <80 mmHg Prehypertension: systolic 120-139 mmHg or diastolic 80-89 mmHg Hypertension:
- Stage 1: systolic 140-159 mmHg or diastolic 90-99 mmHg
Stage 2: systolic ≥ 160 or diastolic ≥ 100 mmHg
Optimal blood pressure: systolic <120 mmHg and diastolic <80 mmHg Normal: systolic 120-129 mmHg and/or diastolic 80-84 mmHg High normal: systolic 130-139 mmHg and/or diastolic 85-89 mmHg Hypertension:
- Grade 1: systolic 140-159 mmHg and/or diastolic 90-99 mmHg
Grade 2: systolic 160-179 mmHg and/or diastolic 100-109 mmHg
Grade 3: systolic ≥ 180 mmHg and/or diastolic ≥ 110 mmHg
Isolated systolic hypertension: systolic ≥ 140 mmHg and <90 mmHg
