A non-invasive fetal ECG was performed on a 36-year-old pregnant woman at 24+6 weeks of gestation as part of ongoing clinical research. A paediatric cardiologist suspected an incomplete bundle branch block based on the averaged ECGs from the recording. The characteristic terminal R' wave was present in multiple leads of the fetal ECGs. A fetal anomaly scan had been performed at 20 weeks of gestation and showed no abnormalities. An incomplete right bundle branch block was confirmed on an ECG recorded at the age of 2 years. This case shows the possibility of novel non-invasive fetal ECG technology as an adjunct to the diagnosis of fetal cardiac anomalies in the future.
作为正在进行的临床研究的一部分，对一名36岁、妊娠24 + 6周的孕妇进行了无创胎儿心电图检查。一位儿科心脏病专家根据记录中的平均心电图怀疑存在不完全性束支传导阻滞。胎儿心电图的多个导联中出现了特征性的终末R'波。妊娠20周时进行了胎儿畸形扫描，未发现异常。在该患儿2岁时记录的心电图上证实存在不完全性右束支传导阻滞。该病例显示了新型无创胎儿心电图技术未来作为辅助诊断胎儿心脏异常的可能性。
