Which symptom is NOT associated with congestive heart failure?

Rapid heartbeat is not a primary symptom associated with congestive heart failure (CHF). In CHF, the heart's ability to pump blood effectively is compromised, leading to various symptoms typically linked to fluid overload and inadequate circulation.

Swelling, or edema, is commonly experienced as fluid accumulates in the body, particularly in the legs, ankles, and sometimes the abdomen. Congestion relates to the accumulation of fluid in the lungs, which can cause difficulty breathing, especially when lying down. Anxiousness can also manifest as a symptom, often as a response to the distress caused by difficulty breathing or the inability to perform daily activities normally due to fatigue and weakness.

While a rapid heartbeat, known as tachycardia, can occur in some individuals due to the body's attempt to compensate for decreased cardiac output, it is not a defining symptom of congestive heart failure itself when directly compared to the more characteristic symptoms of swelling, congestion, and anxiousness.
