Prenatal Diagnosis of High Grade Atrioventricular Block with Polymorphic Ventricular Premature Contractions due to Congenital Long QT Syndrome Using Doppler Flow Recording
We herein report a case of fetal long QT syndrome with a series of cardiac arrhythmias resulting from a 2:1 atrioventricular block and high grade atrioventricular block with polymorphic ventricular premature contractions leading to ventricular tachycardia. These were detected in late gestation using the M-mode and simultaneous Doppler flow recording of the superior vena cava and the ascending a...
متن کاملPrenatal diagnosis of long QT syndrome: implications for delivery room and neonatal management.
This case describes the prenatal diagnosis and integrated peripartum management of a foetus with 2:1 atrioventricular block and torsade de pointes due to congenital long QT syndrome. The unique issues related to the detection of intrauterine conduction abnormalities and ventricular arrhythmias, along with the immediate postnatal care, have been described as an interesting teaching case with suc...
متن کاملFetal Arrhythmias: A Clinical Review
Fetal rhythm abnormalities occur in 2% of pregnancies. They are usually identified by the obstetrician or midwifes after 20 weeks. There are four different methods used to assess fetal arrhythmias: scalp electrodes attached to electrocardiographic recordings, magnetocardiography (FMCG), fetal electrocardiographic recordings from the maternal abdomen, and fetal echocardiography (M-mode, pulsed-D...
متن کاملA variant of long QT syndrome manifested as fetal tachycardia and associated with ventricular septal defect.
Two patients with a novel variant of long QT syndrome are described. The clinical course was characterised by an in utero onset of ventricular tachycardia and atrioventricular block (at 26 and 30 weeks' gestational age, respectively), and an association with a ventricular septal defect. Studies of both patients' families identified relatives with prolonged QT interval, syncope, or sudden death....
متن کاملAn International Study of 287 Patients
Background. The Pediatric Electrophysiology Society studied children with the long QT syndrome (LQTS) to describe the features ofLQTS in patients less than 21 years old, define potential "low-risk" and "high-risk" subpopulations, and determine optimal treatment. Methods and Results. Patients less than 21 years old were included if either QTc was more than 0.44; they had unexplained syncope, sei...
