目的分析重症监护病房中新生儿心律失常的临床特点及预后。方法选取近2年本院重症监护病房中心律失常的新生儿46例，对其采用心电监护等检查手段以明确心律失常的类型，分析其预后。结果交界性心律2例，房性早搏7例，室性早搏4例，室上性心动过速16例，房室传导阻滞7例，室性心动过速10例，可见本实验室上行心动过速的发生机率最高，占34.8%，其次是室性心动过速和房室传导阻滞。经抗心律失常治疗后，43例治愈或好转，3例死亡。结论重症监护病房中新生儿心律失常以室上性心动过速多见，预后多与其原发病的类型及严重程度有关，心律失常的患儿应及时治疗其原发病，选择合理的方法治疗心律失常。“,” Objective: To analyze the clinical features and prognosis of neonatal intensive care unit arrhythmia. Methods: nearly two years of hospital neonatal intensive care unit arrhythmia 46 cases, the prognosis of its type ECG and other tests means to identify arrhythmia analysis. Results: 2 cases of junctional rhythm, atrial premature beats in 7 cases,premature ventricular contractions in 4 cases, 16 cases of supraventricular tachycardia, atrioventricular block 7 cases, 10 cases of ventricular tachycardia seen upstream of the laboratorythe highest incidence of tachycardia, accounting for 34.8%, folowed by ventricular tachycardia and atrioventricular block. After antiarrhythmic therapy, 43 patients cured or improved, 3 patients died. Conclusion: The neonatal intensive care unit arrhythmia supraventricular tachycardia common, prognosis, more than its primary disease type and severity of arrhythmias in children with primary disease should be treated, a reasonable choice of methodtreatment of cardiac arrhythmias.
