Both mother and fetus are at risk when SVT occurs during pregnancy. Pregnancy may predispose to and exacerbate symptoms of SVT which are shortness of breath, palpitations, dizziness and presyncope.
Is SVT normal in pregnancy?
Paroxysmal supraventricular tachycardia (PSVT) is the most common symptomatic arrhythmia during pregnancy. Although PSVT is usually considered transient and harmless, its association with maternal and fetal outcomes during pregnancy are unknown.
What causes fetal SVT?
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.
What is SVT in unborn baby?
Fetal supraventricular tachycardia (SVT) is the most common form of fetal tachycardia. If started early in pregnancy, it can cause non-immune fetal hydrops. Echocardiography is the preferred method for the diagnosis with simultaneous pulsed Doppler recording from the superior vena cava and ascending aorta.
How can I control SVT in pregnancy?
Adenosine is the agent most commonly used during pregnancy, with conversion to normal sinus rhythm in over 80% of cases of acute SVT if non-pharmacological manoeuvres have failed, although manoeuvres such as carotid sinus massage and Valsalva maneuver to control SVT are well tolerated during pregnancy.
Does maternal heart rate affect fetus?
We conclude that brief submaximal maternal exercise up to approximately 70% of maximal aerobic power (maternal heart rate ≤148 beats per minute) does not affect fetal heart rate.
Are beta blockers safe during pregnancy?
β-Blockers are the most commonly used class of medication for treating cardiac conditions in pregnant women. Despite the common use of this class of medication, data that support its safety are limited. β-Blockers cross the placenta and potentially can cause physiological changes in the fetus.
Can SVT be passed down genetically?
SVT is usually a result of faulty electrical signaling in your heart. It is commonly brought on by premature beats. Some types of SVT run in families, so genetic differences may play a role. Other types may be caused by lung problems.
How is SVT treated during pregnancy?
Is verapamil safe in pregnancy?
The drug does pass through the placenta to the fetus, but there have been no reports of fetal complications or birth defects as a result of taking verapamil. Information collected by the Michigan Medicaid Birth Defects Study showed no negative side effects or contraindications for use during pregnancy.
What can you not do while pregnant?

How early can you tell if you’re pregnant?
Most doctors wait until 6-8 weeks to use ultrasound to detect pregnancy, unless there is a medical reason to do so earlier. Detecting pregnancy by listening for the heartbeat with a doppler machine (wand placed on abdomen) cannot be used reliably until at the very earliest 8 weeks, but often closer to 12 weeks.

Is Lamictal safe while pregnant?
Lamictal (Lamotrigine) may not be safe for pregnant women, although current studies are limited to determine the full risks of this medication. Studies conducted to look into the potential effects of Lamictal in pregnancy have shown that this drug may cause few problems.
