Palpitations are best defined as:

Palpitations are best defined as:

• A. Abnormal awareness of a rapid or forceful heartbeat.
• B. Shortness of breath during exertion.
• C. Chest pain with activity.
• D. Fatigue on standing.

Answer: (A)

Palpitations are the abnormal awareness of the heartbeat—perceived as a rapid, pounding, or fluttering sensation in the chest. This is a subjective symptom reported by the person, not a specific rhythm measured on ECG. That makes it the best definition here: the focus is on how the heartbeat feels to the individual, rather than on other symptoms. The other options describe different problems: shortness of breath during exertion is dyspnea, chest pain with activity points to angina, and fatigue upon standing suggests orthostatic intolerance. Palpitations can occur with various causes, including anxiety, stimulants, or actual heart rhythm abnormalities, but the defining idea is that the person feels an abnormal or heightened awareness of their heartbeat.
