Blood flow spectra of left ventricular inflow and outflow of the fetus were measured by pulsed Doppler echocardiography in 82 cases who were diagnosed as fetal arrhythmia clinically. By analysing the order of atrio- ventricular excitation, the spectral characters and the relationship of time- phase, the classification of fetal arrhythmia was confirmed. Among the 82 cases, there were 17 cases of sinus bradycardia, 16 cases of sinus tachycardia, 28 cases of atrial premature beats, 16 cases of ventricular premature beats, 3 cases of II degrees atrioventricular conduction block, 2 cases of atrial fibrillation. These common spectral characters of fetal arrhythmia were confirmed by the examination of neonatal Doppler echocardiography and ECG. This study indicated that this method could be used as one of the diagnostic methods for fetal arrhythmia.
采用脉冲多普勒超声心动图对82例临床诊断为胎儿心律失常的病例进行了胎儿左心室流入和流出血流频谱测定。通过分析房室激动顺序、频谱特征及时间相位关系，明确胎儿心律失常的分类。82例中，窦性心动过缓17例，窦性心动过速16例，房性早搏28例，室性早搏16例，二度房室传导阻滞3例，心房颤动2例。新生儿多普勒超声心动图和心电图检查证实了这些胎儿心律失常的常见频谱特征。本研究表明，该方法可作为胎儿心律失常的诊断方法之一。
