Is it safe to be pregnant and for the baby, if you have episodes of supraventricular tachycardia?

SVT: Svt can be dangerous. Talk to the cardiologist and a perinatologist before even considering pregnanc.

Generally safe: There is little or no risk to the baby if the episodes are brief and well tolerated by mom. However it depends on the frequency, rate and duration of the episodes. More important question is how is the svt controlled, what medications? These may be harmful to the fetus. You need to be followed by an mfm specialist.
