High pressure is systolic blood pressure, low pressure is diastolic blood pressure, if the 70-year-old old man systolic blood pressure of 97mmHg, diastolic blood pressure of 57mmHg, pulse rate of 83 times / min is genetic, thin and other factors, it is normal. It is not normal if it is due to feeding, change in body position, etc. Systolic blood pressure of 97mmHg and pulse rate of 83/min are within the normal range for a 70-year-old, but diastolic blood pressure of 57mmHg is low. If the systolic blood pressure of 97mmHg, diastolic blood pressure of 57mmHg, and pulse rate of 83/min in a 70-year-old person are physiologic low blood pressure caused by heredity, thinness, and other reasons, they are normal. However, if the 70-year-old systolic blood pressure of 97mmHg, diastolic blood pressure of 57mmHg, pulse rate of 83 times / min, is the postprandial blood supply to the cardiovascular and cerebral vessels to reduce, or positional changes lead to sympathetic vasoconstriction abnormality, or the thyroid disease, adrenal insufficiency and other diseases caused by the abnormal, then it is not normal. It is recommended that 70-year-olds undergo regular medical checkups and go to the hospital promptly if they find abnormalities in blood pressure or pulse rate.
