充血性心力衰竭,是指一般静脉充盈压的情况下,心脏不能排出足够的血液来维持身体组织的需要。从血液动力学方面来说,即心脏不能正常地排出从大静脉回流来的血液,因而身体各部分发生血液和体液的郁积。小儿心力衰竭多发生在婴儿期,主要为先天性心脏病所引起。小儿心力衰竭与成人虽无原则上的差别,但临床特点、药物剂量和药物选择等方面,都有其特殊性。 Congestive heart failure, refers to the general case of venous filling pressure, the heart can not discharge enough blood to maintain the body’s needs. In terms of hemodynamics, the heart can not normally discharge the blood returning from the large veins and thus the depressions of blood and body fluids in various parts of the body. Infantile heart failure occurs in infancy, mainly caused by congenital heart disease. There is no difference in principle between pediatric heart failure and adults, but its clinical features, drug dosage and drug selection all have their own particularities.
