title: [Fetal arrhythmias: premature atrial contractions and supraventricular tachycardia].
abstract: Fetal arrhythmias form a complicating factor in 1-2% of all pregnancies and in 10% of those cases morbidity or even mortality is encountered. The most frequent occurring arrhythmias are premature atrial contractions (PAC). These are usually benign phenomena which resolve spontaneously, but require some follow-up to exclude the development of supraventricular tachycardias (SVT). SVTs are rare but are frequently complicated by fetal congestive heart failure or even fetal death. Timely prenatal pharmacotherapeutic intervention is generally advised to return to an adequate heart rate, preferably sinus rhythm. This study reports on the local experience with these forms of pathologies: of the 26 fetuses encountered with PAC or/and SVT between 2003 and 2005, none experienced serious complications, while 6 required pharmacotherapeutic intervention with sotalol.
