Fetal tachycardia is a serious complication in pregnancy that may cause nonimmune fetal hydrops and lead to increased incidences of fetal morbidity and mortality. We report a case of a 28-year-old woman, primigravida, who presented at 26th week of gestation with fetal tachyarrythmia. The pharmaceutical therapy was digoxin which failed to accomplish sinus rhythm and secondly a combination of digoxin with flecainide which restored sinus rhythm after 3 weeks. Fetal hydrops is an ominous prognostic sign and the sooner therapy is initiated, the higher is the conversion rate. At present, there is no ideal treatment protocol for both hyrdopic and non-hydropic fetuses.
