What is the medical term for low blood pressure, which is 90/60 mmHg or lower?

• A. Hypotension
• B. Hypertension
• C. Arrhythmia
• D. Tachycardia

Answer: (A)

The medical term for low blood pressure, defined as a blood pressure reading of 90/60 mmHg or lower, is hypotension. This condition indicates that the force of blood against the walls of the arteries is too low, which can lead to symptoms such as dizziness, fainting, and in severe cases, shock. Understanding hypotension is critical, particularly in clinical settings where maintaining adequate blood flow and perfusion to vital organs is essential for patient health.

In contrast, hypertension refers to high blood pressure, indicating a completely different medical condition characterized by increased force that could lead to complications if left untreated. Arrhythmia describes irregular heartbeats and involves the heart's rhythm rather than blood pressure levels. Tachycardia refers to an elevated heart rate, which can occur for various reasons but does not directly relate to blood pressure measurements. Thus, hypotension is the only term among the options that accurately describes the condition of low blood pressure.
