Prenatal diagnosis and management of fetal Long QT syndrome.

Pediatric Cardiology
Viktor TomekRoman A Gebauer

Abstract

This report describes a fetus presenting with second-degree atrioventricular block, sinus bradycardia, and transient ventricular tachycardia with ventriculoatrial dissociation. Long QT syndrome (LQTS) was suspected due to the association of heart rhythm disturbances and very short transmitral early deceleration time. This impaired relaxation of the left ventricle was explained by the extreme prolongation of the refractory period caused by the prolonged relaxation time. The infant was treated successfully with beta-blockers and implantation of a pacemaker. The prognosis is poor when LQTS presents utero or during the first week of life. To date, only a few case reports of a fetus with LQTS have been published.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
