I had premature ventricular contractions (PVCs) before becoming pregnant, and they worsened slightly during pregnancy. Could you please advise whether premature ventricular contractions in pregnant women affect the fetus?

Whether premature cardiac contractions (premature beats) in pregnant women affect the fetus depends on the severity of the condition. If the patient experiences occasional atrial or ventricular premature beats and the condition improves following psychological adjustment and adequate rest, there is typically no significant impact on the fetus. However, if the condition is severe, it may not only affect the fetus but also compromise the mother’s health.
