A blood pressure of 117/78 mmHg is within the normal range and regular monitoring is recommended. Blood pressures with systolic blood pressure below 140 mmHg and diastolic blood pressure below 90 mmHg are considered to be within the normal range and are not considered to be high blood pressure. A blood pressure of 117/78 mmHg is normal. Hypertension is diagnosed when three measurements of blood pressure not taken on the same day are consistent with a systolic blood pressure ≥ 140 mmHg and/or a diastolic blood pressure ≥ 90 mmHg. If there is a previous history of hypertension and you are using antihypertensive medication, you should be diagnosed with hypertension even though your blood pressure of 117/78 mmHg is in the normal range, and you should still use antihypertensive medication as prescribed by your doctor to maintain your blood pressure at a normal, stable level. To avoid measurement errors, another measurement can be taken 1~2 minutes after the first measurement. For health reasons, long-term blood pressure monitoring is also recommended to observe the overall level of blood pressure. In case of abnormally elevated blood pressure, it is recommended to seek medical attention and treatment according to the doctor’s instructions to avoid delays.
