BACKGROUND: Fetal arrhythmias constitute 10 to 20% of the total referrals to fetal cardiology unit. Ventricular tachycardia (VT) is a rare form of fetal tachyarrhythmia. MATERIALS AND METHODS: This report describes the clinical presentation, diagnostic features, and successful management of VT in a fetus at 32 weeks of gestation. Transplacental therapy with sotalol resulted in the termination of tachyarrhythmia in 48 h, followed by good postnatal outcome. CONCLUSION: Fetal m-mode showing ventricular rate higher than atrial rate with atrio-ventricular dissociation is suggestive of VT. Early diagnosis and institution of transplacental therapy prior to development of hydrops seem to carry a good prognosis even in malignant fetal arrhythmias like VT.
