Fetal Ultrasound Ultrasound is the primary modality for the diagnosis of fetal arrhythmias. The initial ultrasound scan should include measurement of atrial and ventricular rate, determination of whether these are regular or irregular, and whether there is a 1:1 association of atrial to ventricular contraction.Click to see full answer. Correspondingly, what can cause fetal arrhythmia?The cause of most arrhythmias is unknown but some cases may result from an electrolyte imbalance, inflammation, medication or an inherited genetic condition. Severe cases of arrhythmia may be caused by a heart defect such as congenital heart block or by an inherited condition known as long QT syndrome.Likewise, what does fetal arrhythmia sound like? Detection of some dropped or extra beats (arrhythmia) is fairly common, occurring in 1 to 2 percent of pregnancies.

Similarly, it is asked, what does an irregular fetal heartbeat mean? Fetal arrhythmia is a term that refers to any abnormality in the heart rate of your baby. These can include tachycardia–an increased heart rate–or bradycardia, which is a slowed heartbeat. The normal heart rate for a fetus is anywhere between 120 and 160 beats per minute.Is irregular heartbeat normal during pregnancy? Heart palpitations while pregnant This extra blood results in a heart rate that’s about 25 percent faster than usual. A faster heart rate can result in occasional heart palpitations. These feel like your heart is fluttering or beating extremely fast. Heart palpitations can be normal and nonharmful during pregnancy.
