AdministratorWhat is the most common cause of fetal tachycardia?
Common causes of fetal tachycardia include infection, hypoxemia, maternal hyperthyroidism, and tachyarrhythmia. The suspicion for a tachyarrhythmia increases when the fetal heart rate is over 220 BPM.
How common is fetal tachycardia?
Fetal tachycardia, the most common of the rhythm defects, occurs in approximately one in 200 pregnancies.
What is Tachycardic with fetus?
Fetal tachyarrhythmia is an abnormally fast fetal heart rate. In some cases the fast heartbeat may also have an irregular rhythm. Tachyarrhythmia is one of several types of fetal cardiac arrhythmias, congenital heart conditions involving an abnormal heartbeat. The condition is also sometimes referred to as tachycardia.
Is fetal tachycardia normal?
Fetal tachycardia is defined as a heart rate greater than 160-180 beats per minute (bpm). This rapid rate may have a regular or irregular rhythm which may be intermittent or sustained. A sustained fetal tachyarrhythmia is uncommon, affecting fewer than 1% of all pregnancies.
Is tachycardia a fetal distress?
Heart rate abnormalities that are signs of fetal distress: Tachycardia (an abnormally fast heart rate) Bradycardia (an abnormally slow heart rate) Variable decelerations (abrupt decreases in heart rate) Late decelerations (late returns to the baseline heart rate after a contraction)
What causes maternal tachycardia?
Most tachycardia episodes are initiated by ectopic beats and the occurrence of arrhythmia episodes may therefore increase during pregnancy in line with the increased propensity to ectopic activity….Mechanism of arrhythmia.

Can maternal stress cause fetal tachycardia?
Increases in fetal heart rate during the stress test were related to the mother’s overall level of anxiety, but not related to the mother’s own elevated heart rate and blood pressure during the test, the researchers found.
How common is fetal distress?
What is fetal distress? When your doctor or midwife sees signs that your baby is unwell during pregnancy, or isn’t coping well with the demands of labour, they may call it fetal distress. Fetal distress during labour and birth is fairly common. About a quarter of babies show signs of distress at some point .
How do you manage fetal tachycardia?
Fetuses with intermittent tachycardia were treated expectantly. Fetuses with sustained tachycardia were treated with transplacental antiarrhythmic agents alone if heart failure was mild to moderate, and with direct intramuscular therapy if heart failure was severe.
Is tachycardia common in pregnancy?
Tachycardia in pregnancy is common, and distinguishing between physiological and pathological causes can be a challenge. Understanding the cardiovascular changes that take place in pregnancy can help to direct investigations.
What is fetal tachycardia during labor?
Fetal tachycardia is defined as a baseline heart rate greater than 160 bpm and is considered a nonreassuring pattern (Figure 3). Tachycardia is considered mild when the heart rate is 160 to 180 bpm and severe when greater than 180 bpm.
What can cause fetal tachycardia?
– Fetal Anemia – Prolonged fetal movement – Severely Preterm Fetus – Cardiac anomalies – Chronic Fetal Hypoxia
What causes sudden death of fetus in utero?
– Prior surgery to the cervix – Use of illicit drugs, especially cocaine – Fetal abnormalities (genetic or structural problems) – Uterine infection (this is more common in developing countries and less common in the United States) – Physical problems with the uterus, including fibroids or abnormalities in the shape of the uterus
What is the usual and most desirable fetal in utero?
What is the usual and most desirable fetal position in utero? Why is this the most desirable position? head down; because it makes it a whole lot easier on mom and fetus during birth.
What is treatment for fetal tachycardia?
VT in the prenatal situation is rare and can be difficult to diagnose. The fetal heart rate is often relatively normal (180-200bpm) and is usually well tolerated. 8 The treatment of fetal VT includes propranolol, procainamide, and phenytoin.
