Management of tachyarrhythmias in pregnancy
Management of tachyarrhythmias in pregnancy is quite similar to non-pregnant patients, however, the threshold to initiate medications is generally higher. The therapeutic decisions have to take into account the necessity, urgency, timing during gestation, and fetal adverse effects. The first trimester of pregnancy is the most sensitive period for adverse drug effects in fetal development, when a given drug is strictly necessary it should be used at the lowest possible dose. The mother should be counseled on risks and benefits based on current data, acknowledging limitations.
