A systolic blood pressure of 90 to 139 mmHg, a diastolic blood pressure of 60 to 89 mmHg, and a pulse pressure of 20 to 40 mmHg are considered normal at the age of 65 to 70. With increasing age, the elasticity of the blood vessel wall deteriorates, and the blood pressure will increase slightly compared with that of the younger age group, but it should still be within the normal range. The systolic blood pressure range should be 90 to 139 mmHg, and the diastolic blood pressure should be 60 to 89 mmHg. The pulse pressure is the difference between the systolic blood pressure and diastolic blood pressure, and should be 20 to 40 mmHg. Normal blood pressure range if the diastolic blood pressure in the 80 to 89 mmHg and/or systolic blood pressure in the 120 to 139 mmHg for normal high value blood pressure, the development of hypertension increased risk. The middle-aged and elderly population aged 65 to 70 years old are prone to hypertension, simple systolic hypertension, etc. It is recommended that blood pressure be checked regularly, and if there is any abnormality, prompt medical attention should be sought.
