完全性房室传导阻滞指的是冲动从心房到心室的传导过程发生极其严重的障碍,致完全不能通过。它多见于心肌炎(风湿、白喉或其他感染所引起)、冠心病、毛地黄中毒等。见于先天性者极其少见,我国直至1963年才由吴氏首先报道1例,继后王氏等也相继报道1例,但两例均于生后(分别为14月龄和10岁)始获发现,且都伴有明显的心杂音,显然有某种先天性心脏病的存在。最近,我院曾遇1例由胎儿时期即已疑及,并于生后4月即获确诊且不伴其他先天性心脏病者,兹报道如下。陈××,男,4月龄,于1979年9月5日因急性支气管肺炎入院。患儿的母亲怀孕期间,即定期到我院作产前检查,母亲一直感到有胎动,但在听取胎儿心音时,屡因每分钟只能听取60次左右,误以为是母亲的血管搏动而多次错判为“无胎心”,也曾疑及是否有完全性房室传导阻滞的可能。生后发现患儿心率也仅及56次/分。本次入院后,除有因急性支气管肺炎而出现的发热、咳嗽、呼吸促和肺部湿性啰音外,心率也一直在56～60次/分之间,但始终未发现心脏扩大和心杂音现象。心电图检查发现。心房率140次/分,心室率60次/分,呈房室完全分离现象,P波不 Complete atrioventricular block refers to the impulse from the atrium to the ventricular conduction occurs extremely serious obstacles, can not completely through. It is more common in myocarditis (rheumatism, diphtheria or other infections caused by), coronary heart disease, hair yellow poisoning. Found in congenital persons is extremely rare in our country until 1963, Wu was first reported in 1 case, followed by Wang and so on were also reported in 1 case, but both cases were born after (respectively 14 months and 10 years old) were Found, and are accompanied by obvious heart murmur, apparently there is a congenital heart disease. Recently, our hospital had a case of one case that has been suspected since the fetus, and was diagnosed in April after birth and is not associated with other congenital heart disease, are reported below. Chen × ×, male, 4 months old, was admitted to hospital on September 5, 1979 for acute bronchial pneumonia. Her mother’s mother during pregnancy, that is, regularly to our hospital for prenatal care, mothers have been feeling fetal movement, but when listening to fetal heart sounds, often because the minute can only listen to about 60 times, mistaken for the mother’s blood vessels and more The second was sentenced to “no fetal heart”, also wondered whether there is a complete possibility of atrioventricular block. After birth, children found heart rate and only 56 beats / min. After admission, except for fever, cough, shortness of breath, and wet lung rash due to acute bronchial pneumonia, the heart rate has also been between 56 and 60 beats / min but heart enlargement and heart murmur have not been found phenomenon. ECG examination found. Atrial fibrillation rate 140 beats / min, ventricular rate 60 beats / min, was completely separated atrioventricular phenomenon, P wave is not
