3,445 Possible Causes for Arrhythmias Detected Prenatally, Syncope, 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.[karger.com] Long QT syndrome (LQTS) is characterized by prolongation of the QT interval associated with a high risk for syncope and sudden death.[link.springer.com] 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[ncbi.nlm.nih.gov]

  • Tachyarrhythmia

    Overall, these serious tachyarrhythmias comprise less than 10% of arrhythmias detected prenatally.[clinicaladvisor.com] However, the diagnosis, which can vary from benign cases of vasovagal syncope to heart disease related syncope is associated with a more than twofold increase in mortality[caribbean.scielo.org] The changes seen in electrocardiogram (ECG) consist of repolarization abnormalities such as ST elevation, ST depression, negative T waves, and QT prolongation.[ruralneuropractice.com]

  • 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.[glowm.com] The mortality among untreated symptomatic children is up to 70% within 15 years after the first syncopal episode.[af-ablation.org] Obvious concerns include risk of cardiac syncope or SCD.[emedicine.medscape.com]

  • Idiopathic Ventricular Fibrillation

    Abstract A 35-year-old man had a history of recurrent syncope for more than a decade.[ncbi.nlm.nih.gov] Abstract Recent data point to a high incidence of early repolarization abnormalities among patients with idiopathic ventricular fibrillation (IVF).[ncbi.nlm.nih.gov] This report emphasizes that idiopathic VF may be responsible for syncope in children.[ncbi.nlm.nih.gov]

  • Cardiac Arrhythmia

    Electrocardiograms (ECG) were analyzed electronically, and data on syncope, ventricular arrhythmias, and mortality were obtained from administrative health-care registries[ncbi.nlm.nih.gov] In cardiac patients, life-threatening tachyarrhythmia is often precipitated by abnormal changes in ventricular repolarization and refractoriness.[ncbi.nlm.nih.gov] Learn more about syncope.[medstarunionmemorial.org]

  • Long QT Syndrome

    Patients with syncope following intensive emotional stress should be evaluated for malignant arrhythmias in the context of LQTS.[ncbi.nlm.nih.gov] 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[ncbi.nlm.nih.gov] Abstract Long QT syndrome (LQTS) is an arrhythmogenic disorder characterized by repolarization abnormalities with a tendency to cause life threatening cardiac events.[ncbi.nlm.nih.gov]

  • Brugada Syndrome

    The authors report a case in which the diagnosis of Brugada syndrome was made in the course of etiologic investigation of recurrent syncope in a febrile state.[ncbi.nlm.nih.gov] Repolarization abnormalities included a larger area of ST-segment elevation 2 mV and T-wave inversions.[ncbi.nlm.nih.gov] Nineteen patients had a history of cardiogenic syncope, and their EPA and DHA levels were significantly lower than those of the patients without syncope.[ncbi.nlm.nih.gov]

  • Cardiomyopathy

    Dogs diagnosed this way had more VPCs, polymorphic VPCs, couplets, triplets, VTs and R-on-T-phenomenon and syncope, decreased right ventricular function and dilatation in[ncbi.nlm.nih.gov] Clinical diagnosis may be achieved by demonstrating functional and structural alterations of the right ventricle, depolarization and repolarization abnormalities, arrhythmias[ncbi.nlm.nih.gov] The following symptomatology may be seen in patients with HCM: Dyspnea Pre-syncope or syncope Chest pain Orthopnea Dizziness Paroxysmal Nocturnal Dyspnea (PND) Palpitations[symptoma.com]

  • Cardiogenic Syncope

    The recovery after a cardiogenic syncope is usually complete and spontaneous. A careful history inquiry is a key tool in evaluating a syncope patient.[symptoma.com] A twelve-lead ECG performed at rest may show depolarization or repolarization abnormalities such as left ventricular hypertrophy, Wolfe-Parkinson-White Syndrome (WPW), atrial[acc.org] ELECTROCARDIOGRAM The electrocardiogram (ECG) should be carefully evaluated for rate, rhythm and repolarization abnormalities, specifically looking for the long QT syndrome[aafp.org]

    syncope, palpitations, and edema.[ncbi.nlm.nih.gov] The electrocardiogram is abnormal in over 95% of cases; the most common abnormalities include high precordial QRS voltages, secondary repolarization abnormalities (ST segment[radiopaedia.org] abnormalities 42 (61%) 4 (21%) 0.91 LBBB 1 (1%) 0 (0%) NA RBBB 4 (6%) 0 (0%) NA LAH 4 (6%) 0 (0%) NA Normal ECG 13 (19%)* 13 (68%) 0.01 Table 2.[doi.org]
