Fetal arrhythmia refers to any irregularity in your baby’s heart rate, which can manifest as tachycardia (an elevated heart rate) or bradycardia (a slowed heartbeat). The typical fetal heart rate ranges from 120 to 160 beats per minute. This condition is relatively uncommon, occurring in only 1-2% of pregnancies. In most cases, it is temporary and benign. However, there are rare instances where an irregular heart rhythm may lead to more serious complications.
What Are the Causes of Fetal Arrhythmia?
Several factors can contribute to fetal arrhythmia, but in some cases, healthcare providers may not be able to identify the exact cause, particularly if the abnormal rhythm is temporary. Some studies suggest that excessive caffeine intake may cause heartbeat irregularities, so it is advisable for pregnant women to limit their caffeine consumption to about 200mg a day—approximately the caffeine content of a single cup of coffee.
During the second trimester, it’s also common for a baby’s heart to exhibit an irregular rhythm as the electrical pathways develop. This is usually not a cause for concern, unless the irregularity persists for an extended period. In certain cases, arrhythmias could indicate structural abnormalities of the heart, prompting healthcare providers to conduct further tests. If the heart rate is consistently high, medication might be prescribed to help regulate the heartbeat, which can be passed through the placenta to the baby.
Should You Be Concerned About Arrhythmia?
While the exact causes of arrhythmia are still not fully understood, most cases are not life-threatening and tend to resolve on their own. In rare situations where arrhythmia is more severe, the baby could be born with a heart condition that requires ongoing management. There is also a slight risk of fetal death occurring either in utero or during delivery.
Next Steps
The initial step for your healthcare provider will be to monitor the heart rate and overall well-being of your baby. If there are concerns that necessitate further examination, you may be referred to a fetal cardiologist for a more in-depth evaluation.
