Challenge of managing opposing rhythms in a mother and fetus

Chaudhry‐Waterman et al. (2020) conducted a case report in Maternal high grade atrioventricular block and fetal complex congenital heart disease with supraventricular tachycardia (n=2). Electroanatomic mapping for permanent pacemaker implantation and transplacental anti-arrhythmic medications was evaluated on Successful pacemaker implantation with zero radiation exposure and reduction of fetal arrhythmia burden. Electroanatomic mapping allowed successful permanent pacemaker implantation with zero radiation exposure in a pregnant woman, enabling safe delivery of transplacental anti-arrhythmic medications.
