Patient's question:
Today, I went to the local hospital and said that the baby has an irregular heartbeat, occasionally jumping to ninety. Previously, I also had a thyroid deficiency check-up, wondering if it's related to this? When I did the fetal monitoring and 4D ultrasound, the baby's heartbeat and heart were all fine. Why would it have an irregular heartbeat then? What are the symptoms of arrhythmia in newborns?Doctor's answer:
The sinoatrial node is the highest "command center" for the heartbeat, so a normal heart must have a normal sinoatrial node, and a normal sinoatrial node has strong automaticity. The rhythm formed by the excitation of the sinoatrial node is called sinus rhythm. Premature beats are the most common type of arrhythmia, caused by premature beats from an ectopic pacemaker. In healthy people with good physical condition, premature contractions are very common. If they occur occasionally and are asymptomatic, medication is usually not required.
