What health condition is described by a blood pressure reading significantly over normal levels?

Hypertension is a health condition characterized by consistently elevated blood pressure readings, typically defined as a systolic reading of 130 mmHg or higher, or a diastolic reading of 80 mmHg or higher. This condition may result from various factors, including genetics, diet, lifestyle, and stress, and it can lead to various health complications, including heart disease, stroke, and kidney damage if not managed properly.

In contrast, the other options represent different health conditions that do not relate to abnormal blood pressure levels. Hypothermia refers to a dangerously low body temperature, arrhythmia involves irregular heartbeat patterns, and dyspnea describes difficulty breathing. None of these options directly pertain to the measurement or implications of blood pressure, making hypertension the correct choice in this context.
