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.
