本文作者在5年中遇到9例胎儿及乳儿房扑,其中3例(33%)为附加束传导,这多具有病因学意义。方法:自1985年1月至1990年1月,作者发现胎儿及乳儿房扑9例。胎儿房扑的诊断是靠心电图发现规则的房速(400～500次/分)伴房室传导阻滞(通常为2∶1)。新生儿房扑的诊断是体表心电图发现有房扑波,频率为300～500次/分,伴房室传导阻滞,预激证据是靠查看全部心电图,尤其是窦律时的心电图,但未作激发试验来发现隐性预激即诱发心动过速。结果:证实房扑9例,4例胎儿有2例出生前在宫内转复为窦律,这4例胎儿出生后心电图都无预激波。出生时或出生后不久发生房扑的7例中6例有持续心律失常经直流电复律后,房扑未复发,但3
In five years, the authors encountered 9 cases of fetal and atrial flutter, of which 3 (33%) were additional bundle conduction, which was more etiological. Methods: From January 1985 to January 1990, the authors found 9 cases of atrial and fetal atrial flutter. Fetal atrial flutter diagnosis is based on the discovery of the regular ECG (400 ~ 500 beats / min) with atrioventricular block (usually 2: 1). The diagnosis of neonatal atrial flutter is found on the surface ECG with atrial flutter, the frequency of 300 to 500 beats / min, with atrioventricular block, pre-shock evidence is by all electrocardiogram ECG, especially sinus rhythm, but No provocation test to find hidden pre-excitation that is induced tachycardia. Results: Atrial flutter was confirmed in 9 cases, 4 cases of fetus with 2 cases of prenatal transfer of sinus rhythm in the palace, these 4 cases of fetal electrocardiogram after birth without pre-shock wave. Six of the seven patients who developed atrial flutter at birth or shortly after birth had persistent arrhythmia. Atrial flutter did not recur after DC cardioversion, but 3
