How is hypertension defined?

1. Systolic Pressure above 120mmHg and Diastolic Pressure above 80mmHg

2. Systolic Pressure above 150mmHg and Diastolic Pressure above 90mmHg

3. Blood pressure readings of 140/90mmHg or higher

4. Elevated heart rate exceeding 100 beats per minute

The correct answer is: Systolic Pressure above 150mmHg and Diastolic Pressure above 90mmHg

Hypertension, commonly known as high blood pressure, is primarily defined by specific blood pressure readings. According to the American College of Cardiology and the American Heart Association, hypertension is identified when blood pressure readings are consistently at or above 130/80 mmHg. In the context of the options provided, the definition that aligns with the recognized standards for diagnosing hypertension is captured in the reading of 140/90 mmHg or higher. This definition is significant as it highlights the importance of both systolic (the top number) and diastolic (the bottom number) pressures in assessing overall cardiovascular health. The choice indicating systolic pressure above 150 mmHg and diastolic pressure above 90 mmHg is an even higher threshold and does not reflect the earlier guidelines that are now deemed outdated. Similarly, options related to heart rate are not directly indicative of hypertension but may signal other cardiovascular issues. Understanding the thresholds for hypertension is crucial for early detection and management, which can significantly influence patient outcomes in clinical practice.
