Introduction
To diagnose hypertension, blood pressure must be measured at the brachial artery of the upper arm while the patient is seated in a quiet environment. Typically, measurements should be taken on three or more separate days. Hypertension can be diagnosed if the systolic blood pressure is ≥140 mmHg and/or the diastolic blood pressure is ≥90 mmHg. A diagnosis of hypertension also applies if the patient has a prior history of hypertension and is currently taking antihypertensive medication.
As society advances, people’s work-related stress continues to increase. Combined with long-term irregular eating and sleeping habits, alcohol consumption, smoking, and aging, many individuals develop hypertension. The primary symptom of this condition is dizziness; patients with hypertension often struggle to regulate their emotions and become easily irritable. So how is hypertension diagnosed?
How Is Hypertension Diagnosed?
To diagnose hypertension, blood pressure must be measured at the brachial artery of the upper arm while the patient is seated in a quiet, relaxed state. Typically, measurements should be taken on three or more separate days. A diagnosis of hypertension is established if the systolic blood pressure is ≥140 mmHg and/or the diastolic blood pressure is ≥90 mmHg. Patients with a prior history of hypertension who are currently taking antihypertensive medications are also considered hypertensive—even if their current blood pressure readings fall within the normal range. Home blood pressure monitoring may also be used as a reference in the diagnostic process.
For diagnosing hypertension, home-based electronic sphygmomanometers measuring brachial artery pressure, clinically used mercury sphygmomanometers, and 24-hour ambulatory blood pressure monitoring (ABPM) are all acceptable methods. When using a home electronic sphygmomanometer, blood pressure should be measured three times on different days. A reading of ≥140/90 mmHg indicates hypertension; however, home electronic devices require proper calibration and standardized measurement techniques to ensure objective and accurate assessment—otherwise, significant measurement errors may occur. Alternatively, patients may visit a reputable clinic or community health center where mercury sphygmomanometers are used; such measurements are generally accurate and reliable.
We recommend that patients maintain healthy lifestyle habits, follow a light and balanced diet, avoid spicy and irritating foods, and ensure adequate sleep each day. We hope this information proves helpful to you.
