Key result
Fetal congenital LQTS presenting as pulseless VT highlights significant diagnostic and management challenges.
Why the study?
Diagnosis of long QT syndrome in the fetus is rare and can be difficult to manage, with potential progression to significant arrhythmias.
Case Report (n=1)
This case highlights the rare presentation of pulseless ventricular tachycardia in a fetus with congenital long QT syndrome and discusses its diagnostic and management strategies.

Alerts to pulseless VT in fetal LQTS; leaves open evidence-based prenatal strategies pending larger series.
The diagnosis of long QT syndrome (LQTS) in the fetus is rare and can be difficult to manage. Fetuses most commonly present with sinus bradycardia but can develop more significant arrhythmias such as pseudo-atrioventricular block and ventricular tachycardia. Here we report the case of a fetus presenting with "pulseless" ventricular tachycardia in the setting of LQTS, including diagnostic strategies as well as fetal and postnatal management.

Gungor et al. (2026) conducted a case report in Congenital Long QT Syndrome (n=1). Diagnostic strategies and fetal/postnatal management was evaluated. A fetus with congenital long QT syndrome presented with 'pulseless' ventricular tachycardia, highlighting the diagnostic and management challenges of significant fetal arrhythmias.
