Answers: Heart failure within a child could be from a birth defect of the heart.
The child requirements to avoid large amounts of fluid which could worsen the heart fiasco because large amounts of fluid puts extra work on the heart to pump. Low brackish is necessary to control fluid build-up. Bananas are good because they are rich surrounded by potassium and since the child will probably be on diuretics, they need the potassium to be replaced that get lost from all the diuretics. Its best that the child have a dietician plan a good diet depending on how severe the heart breakdown it.
