新生儿心力衰竭(以下简称心衰)是由于某种原因使心脏泵功能减退,导致患儿在安静状态下搏出量不能满足循环及组织代谢需要而出现的一系列病理状态,故也称心功能不全。临床上出现的症状和体征称为心力衰竭综合症,是新生儿期常见的急症之一。一、病因 1、心血管疾病 (1)心肌炎:以病毒性心肌炎最为常见,宫内产道及婴儿室内均可感染。重型常因心衰死亡。(2)阵发性心动过速:无器质性心脏病,心率可达180～300次,经几小时或几天导致心衰,室上性心律失常多见。(3)先天性心脏病继发呼吸道感染最多见,(4)心内膜弹力纤
Neonatal heart failure (hereinafter referred to as heart failure) is due to a certain reason to make the heart pump dysfunction, resulting in children under quiescent volume stroke can not meet the needs of circulation and tissue metabolism and a series of pathological conditions, it is also called cardiac function Incomplete. Symptoms and signs of clinical symptoms known as heart failure syndrome, is one of the common emergency in the neonatal period. First, the etiology 1, cardiovascular disease (1) myocarditis: the most common viral myocarditis, intrauterine birth and infants can be infected indoor. Heavy often died of heart failure. (2) paroxysmal tachycardia: no organic heart disease, heart rate up to 180 to 300 times, after a few hours or days lead to heart failure, supraventricular arrhythmia more common. (3) congenital heart disease secondary to the most common respiratory tract infection, (4) endocardial elastic fibers
