目的:探讨新生儿心律失常的病因、发病机制、临床表现、心律失常的类型和预后。方法:对2008年10月~2013年10月在本科住院并诊断为心律失常的52例新生儿进行临床分析和随访。结果:窦性心律失常23例(44%);窦性心动过缓10例,窦性心动过速13例。异位心律29例(56%);房性室颤9例(频发7例),室上性心动过速4例,室性早搏6例(频发3例);室早并行心律失常1例;室性心动过速4例。各种传导阻滞5例(9%);不完全性右束支传导阻滞2例,I度房室传导阻滞(AVB)1例,II度AVB(文氏型)1例,III度AVB1例。转归心律失常消失43例,占82%(43/52);失访3例,1例死亡。结论:新生儿心律失常多为良性,以窦性心律失常和早搏常见,预后良好;室性心动过速如原发病严重则预后很差。
Objective: To investigate the etiology, pathogenesis, clinical manifestations, arrhythmia types and prognosis of neonatal arrhythmia. Methods: 52 cases of newborns who were hospitalized and diagnosed as arrhythmia from October 2008 to October 2013 were analyzed and followed up. Results: 23 cases (44%) had sinus arrhythmia, 10 cases had sinus bradycardia and 13 cases had sinus tachycardia. Ectopic heart rhythm in 29 cases (56%); atrial fibrillation in 9 cases (7 cases), supraventricular tachycardia in 4 cases, premature ventricular contractions in 6 cases (3 cases); ventricular arrhythmias 1 Cases; ventricular tachycardia in 4 cases. 5 cases (9%) of various types of conduction block; incomplete right bundle branch block in 2 cases, I degree atrioventricular block (AVB) in 1 case, II degree AVB (in type) in 1 case, III degree AVB1 cases. Out of 43 cases of arrhythmia disappeared, accounting for 82% (43/52); lost in 3 cases, 1 case of death. CONCLUSIONS: Most neonatal arrhythmias are benign, with sinus arrhythmias and premature beats common and good prognosis. Ventricular tachyarrhythmias such as severe primary disease have a poor prognosis.
