Which cardiovascular condition is often associated with a "sweaty" infant during feeding?

Congestive heart failure in infants can lead to several clinical signs, one of which is increased sweating, especially during feeding. This occurs because the heart is unable to pump effectively, resulting in increased work and strain during the exertion of feeding. As the body tries to meet the increased oxygen and nutrient demands, it may overproduce sweat as a response to the stress on the body.

In infants, this sweating can also be accompanied by other symptoms, such as poor feeding, irritability, and fatigue, which reflect the underlying inefficiency of the cardiovascular system. The infant may simply not be able to process the demand of feeding due to heart function limitations, leading to signs such as sweating.

Understanding the manifestation of symptoms in congestive heart failure is crucial for prompt diagnosis and management. In contrast, the other conditions listed—such as a simple murmur, myocarditis, and aortic stenosis—may have different presentations and wouldn't typically be associated with sweating during feeding in the same manner.
