What does resting tachycardia (HR >100 bpm) commonly suggest in the screening context?

• A. Potential infection, dehydration, anemia, cardiovascular or pulmonary disease; warrants further assessment.
• B. Always indicates good health.
• C. Only indicates anxiety.
• D. Is normal in most adults.

Answer: (A)

Resting tachycardia is a non-specific sign that prompts you to look for underlying stress or illness rather than assuming everything is fine. When the heart rate stays above 100 beats per minute at rest, it often reflects the body trying to compensate for something else happening. In screening, this commonly points to conditions like infection (often with fever), dehydration (reduced circulating volume), anemia (reduced oxygen carrying capacity requiring higher cardiac output), or problems affecting the heart or lungs (cardiovascular or pulmonary disease). Because many different issues can cause it, this finding signals the need for further assessment: take a thorough history, check temperature and hydration status, review recent medications and stimulants, and perform a focused exam with attention to symptoms such as dizziness, chest pain, or shortness of breath. If tachycardia persists without a clear benign cause or is accompanied by concerning signs, it deserves closer evaluation. It is not an indication of good health, nor is it limited to anxiety, and it is not considered normal in most adults.
