What are the causes of fetal arrhythmia?

Patient's question:

I am more than 31 weeks pregnant. Today, I went to the hospital for an ultrasound examination. The doctor said the fetal heart rate is irregular, changing every 11 beats. The doctor recommended that I go to a higher-level hospital for a screening for congenital heart disease. I am quite anxious. I would like to consult on what could be the cause of the fetal arrhythmia?

Doctor's answer:

If you carefully check and consider it to be fetal arrhythmia, this condition is generally not a major problem. However, because fetal arrhythmia occurs relatively infrequently multiple times, it does not rule out the possibility of congenital heart disease. Therefore, it is recommended to go to a higher-level hospital for further screening or fetal heart monitoring data to understand the frequency of multiple occurrences of this arrhythmia. At the same time, you can perform appropriate oxygenation to stabilize the fetus's nutrition and see how effective stabilization can be achieved.
