| 目的 探讨M型超声结合房室梯形图分析诊断胎儿心律失常的价值。方法 回顾性分析2016年1月至2020年10月期间重庆市妇幼保健院经胎儿超声心动图检查应用M 型超声取样线获取房室壁、房室瓣及半月瓣的活动曲线,结合房室梯形图法分析及诊断胎儿心律失常类型。结果 M型超声结合房室梯形图法共诊断165例胎儿心律失常,其中房性早搏76例(46.1%),室性早搏6例(3.6%),窦性心动过速43例(26.0%),室上性心动过速8例(4.8%),其中房性心动过速1例(0.6%),心房扑动1例(0.6%),窦性心律过缓22例(13.3%),房室传导阻滞9例(5.5%)。结论 M型超声结合房室梯形图诊断胎儿心律失常可行,此方法简单、直观,能明确胎儿心律失常类型。 |

| Abstract: |
| Objective To explore he value of M-mode ultrasound combined with atrioventricular ladder diagram in the diagnosis of fetal arrhythmia. Methods The activity curves of the atrioventricular wall, atrioventricular valve and semilunar valve were obtained in fetal echocardiography with M-type ultrasound sampling line, and the types of fetal arrhythmias diagnosed by atrioventricular trapezoid map were retrospectively analyzed in Chongqing Healthcenter for Women and Children from January 2016 to October 2020. Results A total of 165 cases of fetal arrhythmia were diagnosed by M-mode ultrasound combined with atrioventricular ladder diagram, including 76 cases of atrial premature contractions (46.1%), 6 cases of ventricular premature contractions (3.6%), and 43 cases of sinus tachycardia (26.0%) , 8 cases of supraventricular tachycardia (4.8%), including 1 case of atrial tachycardia (0.6%), 1 case of atrial flutter (0.6%), 22 cases of sinus bradycardia (13.3%), atrial Ventricular block was found in 9 cases (5.5%). Conclusion M-mode ultrasound combined ith atrioventricular ladder diagram is feasible to diagnose fetal arrhythmia. This method is simple and intuitive, and can identify the type of fetal arrhythmia. |
