What is Systolic Blood Pressure (Upper Blood Pressure)?
Also written as：Maximum blood pressure ／ Upper blood pressure
Systolic blood pressure is the pressure in the arteries when the heart contracts and pumps blood throughout the body. Also known as the "upper" blood pressure reading, it represents the peak pressure exerted on the arterial walls and is a key measure in evaluating hypertension.
Reference range guideline
A reading of 140 mmHg or higher in a clinical setting, or 135 mmHg or higher at home, is considered a threshold for hypertension (assessed together with diastolic blood pressure).
* Reference ranges vary by testing facility, measurement method, age, sex, and other factors. Please check the reference range printed on your result sheet.
How to interpret an out-of-range result
Consistently elevated readings may indicate hypertension. A single measurement is not sufficient for a diagnosis — confirmation through home blood pressure monitoring or repeat measurements is recommended.
