文本框: AN ANALYSIS OF 89 CASES OF SERIOUS ARRHYTHMIA OF NEWBORN BABIES AND BABIES Zhang Y-Z，Wang H-Y，Na Q Women and Children Health Hospital of Inner Mongolia Autonomous Region, Hohhot, Inner Mongolia, China Objective: To make a research on the causes of serious arrhythmia of newborn babies and babies. Methods: All the cases were checked by ECG and monitored by electrocadiograph and were confirmed as cases of arrhythmia. The patients also received ultrasoundcardiogram and chest X-rays checks. We mainly did LDH-MB in serum myocardial enzym testing in 1994-1998. We did CK-MB in 1998-1999. Result: The 28 cases of congenital heart disease (15 cases of newborn babies, 13 cases of babies) are of complex congenital heart disease. 32 cases of suffocation are newborn babies, 76.6% of them are serious suffocation. 10 cases are encephalomyocarditis, 6 cases preexcitation sydrome. All the patients are babies. N0 exact cause: 3 newborn babies lack identifiable cases. As for the arrhthmia types: 25 cases of suprarentricular tachycardia; 27 cases of cotrial premature beats with paryoxysmal tachycardia; 15 cases of sinus bradycardia; 15 cases of atrial premature ventricular beats; 2 cases of wenckebach block; 3 cases of atrial fibrillation; 2 cases of atrial flutter. Most of myocardial enzym is of LDH1/LDH2>1, CK-MB increase>=7%. Conclusion: The main causes of newborn babies disease is serious suffocation, the second cause is complex congenital heart disease. As for Babies, congenital heart disease is the main cause and the others cndocardium myocardosis and encephalomyocarditis. 0764
