5,761 Possible Causes for Arrhythmias Detected Prenatally, Tachycardia, Ventricular Repolarization Abnormalities

  • Long QT Syndrome 13

    Hsiao et al. [ 30 ] analyzed the outcomes of 123 fetuses with prenatally detected cardiac malformations and/or cardiac arrhythmias.[] Monitor revealed a wide complex, polymorphic ventricular tachycardia, which reverted to sinus rhythm in a span of few seconds.[] RESULTS: Compared with the analysis of the healthy group (n 8), age- and sex-matched pair analysis revealed that the mutation carriers (n 8) had ventricular repolarization[]

  • Tachyarrhythmia

    Overall, these serious tachyarrhythmias comprise less than 10% of arrhythmias detected prenatally.[] We describe a neonate that developed alternating wide and narrow complex tachycardias following heart surgery for congenital heart defect.[] The changes seen in electrocardiogram (ECG) consist of repolarization abnormalities such as ST elevation, ST depression, negative T waves, and QT prolongation.[]

  • Incessant Infant Ventricular Tachycardia

    Supraventricular Tachycardia SVT is the most common serious arrhythmia detected prenatally. It accounts for about 6% of referrals, as shown in Table 2.[] The finding of wide QRS tachycardia with retrograde block confirms the diagnosis of ventricular tachycardia.[] Ventricular tachycardia may also occur in children with long QT-syndrome wich is a familial disease carachterized by prolonged and abnormal ventricular repolarization and[]

  • Cardiac Arrhythmia

    In 30 of 32 patients (94%) with an inducible tachycardia during invasive EPS, it was also possible to induce the tachycardia by TAS.[] In cardiac patients, life-threatening tachyarrhythmia is often precipitated by abnormal changes in ventricular repolarization and refractoriness.[] Repolarization abnormalities in cardiomyocytes of dogs with chronic heart failure: role of sustained inward current.[]

  • Long QT Syndrome

    LQTS indicates long-QT syndrome; CPVT, catecholaminergic polymorphic ventricular tachycardia.[] Compared with the analysis of the healthy group (n 8), age- and sex-matched pair analysis revealed that the mutation carriers (n 8) had ventricular repolarization abnormality[] Abstract Long QT syndrome (LQTS) is an arrhythmogenic disorder characterized by repolarization abnormalities with a tendency to cause life threatening cardiac events.[]

  • Arrhythmogenic Right Ventricular Dysplasia

    A left bundle branch block inferior axis tachycardia was manifest.[] We hypothesized that ventricular depolarization and repolarization abnormalities on the 12-lead surface electrocardiogram (ECG) predict adverse outcome in patients with ARVD[] A 42-year-old male had history of recurrent palpitation and was documented to have wide QRS tachycardia.[]

  • Brugada Syndrome

    In electrophysiological study he developed right ventricular outflow tract tachycardia provoked by combined infusion of ajmaline and orciprenaline.[] Repolarization abnormalities included a larger area of ST-segment elevation 2 mV and T-wave inversions.[] This report documents a case of Brugada syndrome and polymorphic ventricular tachycardia-ventricular fibrillation not initially recognized in a patient taking nortriptyline[]

  • Torsades De Pointes

    This electrophysiological abnormality may lead to syncope or sudden cardiac death due to rapid, polymorphic ventricular tachycardia (VT).[] Performing periodic ECGs with prompt removal of offending agent when repolarization abnormalities are appreciated is ideal.[] Polymorphic Ventricular Tachycardia 12-lead ECG Example[]

  • Cardiomyopathy

    Junctional ectopic tachycardia (JET) is a rare form of arrhythmia that is most commonly seen during infancy.[] Clinical diagnosis may be achieved by demonstrating functional and structural alterations of the right ventricle, depolarization and repolarization abnormalities, arrhythmias[] Case 2 presented isolated LVNC with nonsustained ventricle tachycardia. A cesarean section was performed at 36 weeks' gestation because of placenta previa.[]

  • Supraventricular Tachycardia

    […] the tachycardia.[] An example is hypertension and LV hypertrophy that accompany renal failure and are associated with abnormal ventricular ( 513 ) and atrial ( 514 ) repolarization.[] Tachycardia means fast heartbeat and supraventricualr means the region above the ventricles.[]
