ABSTRACT

Introduction: fetal electrocardiography is the gold standard for diagnosis of arrhythmias in postnatal life. This is difficult to achieve in prenatal life even with high-resolution prenatal ultrasound. Supraventricular tachyarrhythmias are manifested with heart rates above 180 beats per min and may be associated with fetal death in one third of cases, especially when associated with fetal hydrops or when it is set for over 15 days. Treatment allows the reversal of ventricular arrhythmia or control in the shortest possible time.
Objective: to test tachyarrhythmia in uterus response to drug treatment.
Methods: An observational prospective descriptive study was conducted in a universe of 24 fetuses with the diagnosis of fetal tachyarrhythmia that were diagnosed and treated at the Provincial Department of Genetics, Havana and at the Ramón González Coro Maternal Hospital from 2003 to 2012.
Results: tachyarrhythmias were observed in 24 fetuses (40.6 %). Mothers younger than 30 were the most represented in this study group, together with BMI overweight and nulliparous patients specifically. Almost half of the sample did not require drug (45.8 %) treatment, all with extrasystoles echocardiographic diagnosis and only one with organic heart involvement.
Conclusions: flecainide was used in a quarter of the sample and showed 83.3 % resoluteness of fetuses in uterus. Survival of fetuses pharmacologically orally treated was 100 %.
