我院于1992～1997年收治新生儿窒息162例,其中49例有心肌受累的临床表现,现分析如下。 临床资料:本组49例,出生时Apgar评分0～7分。主要临床表现为心音低钝、心率减慢或增快、呼吸增快、青紫、苍白和肝肿大等。患儿生后6～72小时均有心电图异常改变,其中两个以上导联ST段移位33例,T波低平或倒置49例,室性期前收缩3例,窦性心动过速4例,窦性心动过缓3例,Q—T时间延长9例,束支传导阻滞2例,P—R间期延长及异常Q波各1例。生后3天内测定心肌酶谱,其血清肌酸磷酸肌酶(CK)平均11.20U/L,心型同功酶(CK—MB)0.52U/L,乳酸脱氢酶(LDH)9.62U/
Our hospital in 1992 to 1997 admitted 162 cases of neonatal asphyxia, of which 49 cases of myocardial involvement clinical manifestations are as follows. Clinical data: The group of 49 patients, birth Apgar score 0 to 7 points. The main clinical manifestations of blunt low heart rate, heart rate slowed down or faster, faster breathing, bruising, pale and hepatomegaly. 6 to 72 hours after birth in children with abnormal ECG changes, of which more than two lead ST segment displacement in 33 cases, T wave low flat or inverted 49 cases, 3 cases of premature ventricular contractions, sinus tachycardia 4 Cases, sinus bradycardia in 3 cases, Q-T extended in 9 cases, bundle branch block in 2 cases, P-R interval and abnormal Q wave in 1 case. Myocardial zymogram was measured within 3 days after birth. The serum creatine phosphokinase (CK) averaged 11.20U / L, cardiac isozyme (CK-MB) 0.52U / L, lactate dehydrogenase (LDH) 9.62U /
